Add filtermap to the standard library Rust, Elixir and other functional languages have this and it would be nice to have an alternative to the option allocating choose function: let filtermap (filter:a->bool) (map: a->b) (xs: a list) -> b list = ... Elixir:http://elixir-lang.org/docs/v1.0/elixir/Enum.html#filter_map/3 Rust: https://doc.rust-lang.org/std/iter/trait.Iterator.html#method.filter_map

Looks like the uservoice is no longer available. Is there a way to get the comments back?

This archive link works https://github.com/fsharp/fslang-suggestions/blob/d48c35ce216e2bff148937ec028ad61e5c273fdf/archive/suggestion-11544387-add-filtermap-to-the-standard-library.md

Also I would mention that I tend to use choose whenever I have a "map something based on a condition" scenario.

@kerams perfect!

@cartermp thanks! I did eventually find choose. I was thinking having the original comments here might help other people with the same question.

Is it possible to remove the original broken uservoice links (or strike them out or whatever).
