Yes. I have submitted a few (very few) which have been well received. Last I noticed, I think I was credited with something like 0.0008% of all of perl (or maybe that was just of the recent changes to perl) - which pleased me out of all proportion to the smallness of the number. I have started on some patches to doc:/perldata and perlop covering what has been discussed here (and elsewhere) and will submit them if I get to the point I think they are worthy.
