You need that (...)[0] for the match to return the captures in list context, ( <=> is enforcing scalar context and m// only returns captures in list context otherwise boolean )

I'm wondering if there is a prettier solution for that.

The Schwartzian transform doesn't have that limitation.

... map { [$_, /(\d+),/] } @list;

should do already.

update

clarification: any better solution than (...)[0] to get list context ?
