This recent post in r/programming poses an interesting question for a bit of golf: "What is the shortest word in the English Language which contains: a b c d e f?" Some Junk™ code was posted to figure this out and my Perl version is a bit shorter. I know you perl better than me, if you do, and can see how else to do this:

The Junk Code:

sorted([w.strip() for w in open('/usr/share/dict/words', 'r').readline
+s()
if set(list('abcdef')).issubset(set(list(w.strip())))], key=lambda x: 
+len(x))
[download]

My Perl Port:

open$:,"</usr/share/dict/words";while(<$:>){next unless/(?=.*a)(?=.*b)
+(?=.*c)(?=.*d)(?=.*e)(?=.*f)/i;push@_,$_}@_=sort{length$a<=>length$b}
+@_'
[download]

For your convenience:

Print the list:

open$:,"</usr/share/dict/words";while(<$:>){next unless/(?=.*a)(?=.*b)
+(?=.*c)(?=.*d)(?=.*e)(?=.*f)/i;push@_,$_}print for sort{length$a<=>le
+ngth$b}@_
[download]

Print the word:

open$:,"</usr/share/dict/words";while(<$:>){next unless/(?=.*a)(?=.*b)
+(?=.*c)(?=.*d)(?=.*e)(?=.*f)/i;push@_,$_}for(sort{length$a<=>length$b
+}@_){print;last}
[download]

Compare length of Perl to Junk:

#!/usr/bin/perl -lw
use strict;

my $PERL = <<'PERL';
open$:,"</usr/share/dict/words";while(<$:>){next unless/(?=.*a)(?=.*b)
+(?=.*c)(?=
.*d)(?=.*e)(?=.*f)/i;push@_,$_}@_=sort{length$a<=>length$b}@_'
PERL

{ no strict;

$JUNK = <<JUNK;
sorted([w.strip() for w in open('/usr/share/dict/words', 'r').readline
+s()
if set(list('abcdef')).issubset(set(list(w.strip())))], key=lambda x: 
+len(x))
JUNK

print length $PERL, ' PERL: ', $PERL;
print length $JUNK, ' JUNK: ', $JUNK;
}

# I think junk could lose 4 spaces making it 148.
__END__
PERL: 144
JUNK: 152

Of course different versions of dict give different results...
