in reply to PGA Golf, Round 1

I did slightly better in a couple of places, so probably wrong. I'll submit it now, before better solutions show up for everything. (Corrected holes 3 and 4 as per more-careful-readers-of-specs.)
# hole 1: 16 perl -le 'sub h1 {(pop=~/\w+/g)[4]}' -e'print h1"abc ,., de f g + hi jk"' # hole 2: 20 perl -e' goto TPC' # hole 3: 19 perl -le 'sub h3 {pop=~/^(.+?)\1+\z/s}' -e'print h3 join" ",qw(hihi +hihi)' # hole 4: 19 perl -le 'sub h4 {split"",pack"H*",@_}' -e'$,=$";print h4"68696C6f" +' # hole 5: 22 XXX see below: perl -le 'sub h5 {$_<$x or$x=$_ for@_;$x}' -e'print h5(3,5,2,8,7)' # hole 6: 38 perl -le 'sub h6 {grep{s/.//}sort map{/[aeiou]/;$&.$_}@_}' \ -e'$,=$";print h6 qw(book eel hi huge i pe +a wrap)'
oopsdate: Yes, 5 doesn't work w/o priming the temporary (which makes it 30 chars).
So, here's an overly golfish version that I managed to trim to 32:
perl -le'sub x {$_[-1]<$_[0]?pop:shift;$#_?&x:@_}' -e'print x(-3,-5,-2 +,-8,-7)'
(And yes, by the time I posted them, the solutions were all pretty much established. jmcnamara said he wasn't posting answers for a week, so it's a guess between not posting 'spoilers' and getting 'rep' -- especially when others are updating as you collect and cut and paste.  --  Anyway, it is kinda neat that, at least for these first few, the straightforward solutions are the best.)
