in thread Regexp not capturing in named subrules

However, what puzzles me and should be apparent is that nothing at all was captured.

    Since the "leftmost defined buffer" is inside of a group quantified by {0}, it isn't puzzling to me that this buffer didn't match. And it isn't surprising that a buffer that didn't match doesn't capture anything.

    Perhaps you were now expecting thing => undef, contrary to your previously stated expectation? If so, my limited testing shows that %+ keys aren't pre-populated but the values are returned by magic (%+ always appears empty even when $+{moo} returns "o" after 'cow' =~ /(?<moo>o+)/).

    Update: I'm glad to report that the lack of keys in %+ appears to have only been an effect of the quick-hack method I used to test, related to evaluation order problems.
