Feature #9253: Regexp named match and case statement

• Status: Open
• Assignee: -

Hello,

I've notice there's no mean to use captured named matches with case
statement :

> a, b = "foo bar", nil
=> ["foo bar", nil]

>   case a
>     when /foo (?<b>bar)/ then p b
>   end
nil

This is not critical, because we can use $1, $2 and friends in place, but it
certainly would be nice and less surprising if it worked.

NB : btw, the link "How to report" [1] from tracker home page [2] is a 404.

There is a way to capture it: use $~[:b] instead of b. Nonetheless, I like this proposal.

I didn't know of this syntax, thanks Yusuke.

Indeed, I did not know of $~[:b] either. Quite nice.
