Before everyone rushes out to defend golfing (too late), consider this...

When I golf, and I am guessing this is pretty typical, I basically slap some line noise together, and see what happens when it runs. I might edit and execute my program hundreds of times, but this is no biggee...I have a syntax highligting editor that catches typos, a shell with command line history, a windowing OS, browser open to hyperlinked man pages, and my own box with cycles to burn. If I get too clever and screw something up, I spend 99% of my time debugging, and almost none wrestling with the environment.

Now consider the programming environment of 1972. Punch cards, line editors, batched jobs on shared mainframes, byzantine manuals on dead trees...editting, compiling, executing code, and reading docs was a pain in the ass. It could literally take hours to learn your program had a fatal one character typo.

Given all this, I think I would stay aware from "clever" progamming languages, too. At least for a little while...:)

    [Cosmic37]: greetings earthlings please can someone improve my pathetic perl knowledge
    [Cosmic37]: I have 2 files each with datetime and other data in unknown order and I want to find rows from both files matching by datetime and output them combined/ concatenated
    [Corion]: Sure
    [Corion]: Do you have any specific interests or general Perl knowledge?
    [Cosmic37]: should I slurp? should I grep? Noble Lords I wish you good karma and beg your advice
    [Corion]: Cosmic37: Ah, see perlfaq4, about How do I compute the intersection of two arrays
    [Cosmic37]: I am out of practice; I use Perl for scientific programming for number crunching
    [Corion]: Cosmic37: Basically, you read one file into a hash, keyed by your key, and then match the lines from the second file to that hash
    [Cosmic37]: note that the two files only have datetimes which may match whereas other data per line is different format in file1 and file2 - is that really intersection?
