--- Comment #3 from Vlad Levenfeld <vlevenf...@gmail.com> --- I'm not sure its such an anti-feature - I keep having "cannot infer argument types" bugs using foreach on custom ranges, and zipping them with an enumeration sequence beforehand seems a pleasant nice enough workaround. (To be fair this may be fixed in 2.067 but I don't know because 2.067 segfaults on my codebase and I haven't had time to hunt down the cause yet.) In any case I feel it should either be documented or removed because it caught me by surprise and took a little bit of time to figure out what was going on, mainly because the lack of documentation. --
