in reply to Re^3: matching a regular expression
in thread matching a regular expression

What I meant was, writing "h|hs|hsb|hsbn" yourself is tedious. Better to have Perl generate that for you: 
my %abbrevs = map {
  my $word = $_;
  ($word => join("|", map { substr($word, 1, $_) } 1 .. length($word) 
+}))
} qw( hsbn admin ... );

    Thanks. I agree it seemed tedious, but no better method was jumping to mind. I like that solution!
