    Other than looking like some of the spam I receive, nice job :)

    Here is a dumb hello world:
    s RRprint q qHelloX WorldY
    qR and s RXRchr oct oct ord BRe and s RYRchr oct oct oct oct ord MRe and eval
    
    From that everybody can construct their own alphabetic code.
      Pity it's anonymous.. This is nice.

    Well, here's the start of the ripping apart of this cool piece of text. I don't currently have the time to reverse engineer the whole thing, I may come back to it later if nobody else does so first:

    s//ucfirst/e and s/c/ chr oct hex acdac/eg xor s/o/ study dive/eg and s/\n//g and s/r /oo do reverse / xor s/o do/chr reverse ord srand hyper/e and s/s/lcfirst/eee if s// ILwHChJwulrZrjqBkNAsAoXVcFMopbloPRZAcwJMcAcR ogctmccXVNgNLoorWVPvJoPocohNPoaccoSRcQWMcqwWAngtc ugnAKocovocoKxSLdiocEocTJTMYobcTJEcTcZocccDBcbEjc oWRABvGZoYoVcfAnaoooAQATJnbLcoCoHzuPyJQIaIWNLqSxs Lwr/x

      My /eee foo is weak. I have absolutely no clue what a /eee switch does on a regex. Here's what I've worked the whole thing down to and I don't understand how it works its magic. I know that /eee is on the perl purity test, but I'm still clueless :|

    I Can't Believe It's Not Text! (excellent, and I have absolutely no idea how this works or what magic can be done with s here...)

    Cool, but it coredumps on 5.8.0.
    (but I guess it is more related to the perl version than to your code :-) ).
    On 5.6.1 it works OK.

    I dislike the large amount of warnings I get. It's nice to see no special characters are used, like " and $ and such.

    And so great it does not use the length trick:

    s kdkchr oct hex hex hex hex length dbmopentutjavaisevilbutmarksegand s smschr hex hex length nooriginalideasegand eval for lc printmqqmbdujustmanothermduperlmhackerdnb

    Small change (to fit in an sms):

    s kdkchr oct hex hex hex hex length qr hypergeomopenclosehksegand s smschr hex hex length qr open cosegand eval for lc printmqqmbdujustmanothermduperlmhackerdnb

      Let me make it even shorter:

      s kdkchr oct oct hex cekegand s lmlchr hex hex hex elseg and eval for lc printmqqmbdujustmanothermduperlmhackerdnb

      Update: even a bit more shorter:

      s kdkchr oct oct hex cekegand s lmlchr oct hex ffflseg and eval for lc printmqqmbdujustmanothermduperlmhackerdnb

      And here's a list of ways of representing numbers in short code consisting of only lc letters and space:

      The list has been updated.

      -5 = log cos hex b -4 = log sin hex affff -3 = log cos ord c -2 = log cos ord f -1 = log sin ord t 0 = cos ord b 1 = length z 2 = log hex c 3 = length zzz 4 = log ord e 5 = log hex be 6 = oct ord uc e 7 = log hex aff 8 = oct ord l 9 = oct ord w 10 = hex a 11 = hex b 12 = hex c 13 = hex d 14 = hex e 15 = hex f 16 = hex hex a 17 = hex hex b 18 = hex hex c 19 = hex hex d 20 = hex hex e 21 = hex hex f 22 = hex hex hex a 23 = hex hex hex b 24 = hex hex hex c 25 = hex hex hex d 26 = oct oct hex fff 27 = oct hex hex hex f 28 = oct hex daa 29 = oct hex dff 30 = oct hex hex aa 31 = oct oct oct hex daaa 32 = oct hex fff 33 = hex hex hex f 34 = oct hex ffffffff 35 = hex hex hex hex b 36 = hex hex hex hex c 37 = oct oct hex daaa 38 = oct oct hex hex ee 39 = oct oct ord ord c 40 = oct ord hex dd 41 = oct hex caaa 42 = oct ord hex fff 43 = oct oct ord uc a 44 = oct ord hex ffff 45 = oct hex daaa 46 = oct hex hex ee 47 = oct ord ord c 48 = ord cos ord k 49 = ord ord o 50 = ord hex dd 51 = ord hex eaa 52 = ord hex fff 53 = oct ord uc a 54 = ord hex ffff 55 = ord ord uc n 56 = ord ord uc p 57 = ord ord c 58 = oct ord uc h 59 = oct ord uc i 60 = oct ord uc j 61 = oct ord uc k 62 = oct ord uc l 63 = oct ord uc mz 64 = oct ord d 65 = ord uc a 66 = ord uc b 67 = ord uc c 68 = ord uc d 69 = ord uc e 70 = ord uc f 71 = ord uc g 72 = ord uc h 73 = ord uc i 74 = ord uc j 75 = ord uc k 76 = ord uc l 77 = ord uc mz 78 = ord uc n 79 = ord uc o 80 = ord uc p 81 = ord uc qz 82 = ord uc r 83 = ord uc sz 84 = ord uc t 85 = ord uc u 86 = ord uc v 87 = ord uc w 88 = ord uc x 89 = ord uc yz 90 = ord uc z 91 = oct oct hex cd 92 = oct oct hex ce 93 = oct oct hex cf 94 = oct hex hex dff 95 = oct hex ord uc yz 96 = hex oct ord uc j 97 = ord a 98 = ord b 99 = ord c 100 = ord d 101 = ord e 102 = ord f 103 = ord g 104 = ord h 105 = ord i 106 = ord j 107 = ord k 108 = ord l 109 = ord mz 110 = ord n 111 = ord o 112 = ord p 113 = ord qz 114 = ord r 115 = ord sz 116 = ord t 117 = ord u 118 = ord v 119 = ord w 120 = ord x 121 = ord yz 122 = ord z 123 = oct hex ad 124 = oct hex ae 125 = oct hex af 126 = oct oct hex ord h 127 = oct oct hex ord i 128 = hex ord uc p

      Update: oh, I forgot those ending with ord plus a letter and ord uc plus a letter, I'll check for those later. -- update: done now

      I, however, did check the ones with length qr jzzz...zzzj which could help as qr increases the number with 9 for only 5 char's cost, but it turns out that it's never the shortest.
