I'm just wondering if having holes in the resulting array is a good idea.
It may complicate reading dumps and forces using "foreach" vs "for". I'm
also wondering if the original proposal wouldn't be better (having NULL for
*all* nonmatches, even trailing ones), if possible.
Anyway, I'm fine with either. It's just out of my skills right now so feel
free to take over my PR ... sorry.
