18:23:30pjbNotThatRPG: the point of iterate is to be extensible, so has it or has it not it doesn't matter, you can add it if it doesn't have it already.
18:23:31_deathisn't it already possible using its extension facilities? if you make it a "built-in" feature, it means new code that uses it is no longer compatible with old iterate versions
18:24:38NotThatRPG_death: Yes, you are right. One could even have a small add-on library for such extensions (e.g., mean, medium, mode)
