The question was for a match in list context
(@match) = ( $_ =~ /.../g )
which returns the matches as a list into an array.
i.e. $match[0]=$1 ( see perlop ¹ )
I didn't want to confuse with more details than necessary...

well actually the /g modifier isn't necessary and might produce too many matches...
DB<110> @matches = ('abcd' =~ /(.)(.)/) => ("a", "b") DB<111> @matches = ('abcd' =~ /(.)(.)/g) => ("a", "b", "c", "d") DB<112> $matches[0] => "a"

* Matching in list context
If the "/g" option is not used, "m//" in list context returns a list consisting of the subexpressions matched by the parentheses in the pattern, i.e., ($1, $2, $3...).
