Hmm, I meant this line of the OP's code: `my @nums = $data =~ /\d+/g;` I think it can be called an assignment to an array, which imposes a list context on the right-hand side, as it is described in perldata: Assignment to a scalar evaluates the right-hand side in scalar context, while assignment to an array or hash evaluates the righthand side in list context. Assignment to a list (or slice, which is just a list anyway) also evaluates the righthand side in list context. I think this would be an assignment to a list: `my ($num) = ...` [download]	[reply] [d/l] [select]
