Dear Monks,

my question today is of utter importance for my project. Probably the answer to it will be "you'll have to code it yourself". That'll be ok for me, but I hope I understand all aspects of the problem before I do so. Hence my question:

The Set::Scalar module provides nifty set-functionality. One of the methods is has which returns true if a given element (you give it as a parameter to that method) is member of the set.

my $s = Set::Scalar->new('a','b','c(d)');

print $s->has('a'); # returns true
[download]

The functionality I desperatedly need would be:

my $s = Set::Scalar->new('a','b','c(d)');

if($s->has(/c\((.+)\)/)) {
  print $1;           # prints 'd'
}
[download]

My concrete questions are:

• Does this already work and I'm doing something wrong to achieve my goal?
• If this doesn't work, would it be an interesting extension to the Set::Scalar module?
• If this extension seems not worthy: How to alternatively implement that?

I owe you much.

Bye
 PetaMem
