Perl: sort string alphabetically, or remove dupe chars?

[Nikolas Britton]

basically what I want to do:

my @wordlist = (letter, remember, alphabetically);
## some whizbang code that changes words like
## "letter" to "eelrtt", remember to beeemmrr,
## and alphabetically to aaabcehilllpty.
@foobar =~ tr///cs; #hmm, doesn't work.
print "@wordlist\n";

Hmm, that's broke, how about this:

my $wordlist = "letter";
## some whizbang regex that removes dupe chars
## from words like "alphabetically" --> "alphbeticy".
print "$wordlist\n";


Thanks.
