Someone asked on Perlmonks if a hash could do fuzzy matches on keys - this
|
|
is the result.
|
|
|
|
If there's no exact match on the key that you pass to the hash, then the
|
|
key is treated as a regex and the first matching key is returned. You can
|
|
force it to leap straight into the regex checking by passing a qr'ed regex
|
|
into the hash like this:
|
|
|
|
my $val = $h{qr/key/};
|
|
|
|
exists and delete also do regex matching. In the case of delete all vlaues
|
|
matching your regex key will be deleted from the hash.
