I think I said in the RFC, didn't I? It's extending the counting use of tr///
to allow you to count several different letters at once. For instance, letter
frequencies in text is an important metric for linguists, codebreakers and
others; think about how you'd get letter frequency from a string:
$as = $string =~ tr/a//;
$bs = $string =~ tr/b//;
$cs = $string =~ tr/c//;
...
$zs = $string =~ tr/z//;
Ugh.
(%alphabet) = $string =~ tr/a-z//;
Yum.
And it's on the Perl 5 wishlist, so it ain't just me that thinks its a worthy
idea.
