How can I extract the matches from the Perl match operator into variables?

Question

If I have a match operator, how do I save the parts of the strings captured in the parentheses in variables instead of using $1, $2, and so on?

Answer 1

Use the bracketing construct (...) to create a capture buffer. Then use the special variables $1, $2, etc to access the captured string.

if ( m/(interesting)/ ) {
    my $captured = $1;
}
