(also, a bunch of existing solutions just got trashed by the null yields test... rip)

thanks, i've added your new tests. i've also added a note to the description warning that yielded values may be null

this kata isn't really meant to test for multiple threads of execution, but i suspect using static variables to store generator-specific data will likely fail in cases with multiple generators anyways

Tags are mostly automatic (and bad, yes), don't post suggestions about that, it's useless. Thx.

Most tags are automatic (and wrong, yes). Nobody is "editing" them.

Please don't open issues about tags. That's ridiculous. Idk who edits the tags but it has nothing to do with an issue with the kata. Suggestions, maybe, but not issues.

This is a suggestion, not an issue.

Sorry, I hope it's fixed now because I could never reproduce the original issue.
