Yes you are indeed correct about the complexity. I was simply trying to highlight that with a filter |> map solution, you would have to iterate over the list twice (in the worst case), although it would be the same amount of function invocations which would make up the bulk of the computations anyway. With a comprehension style solution (like filter_map) the list would only have to be iterated over once. However, I agree with your other points and I think that what I’m saying about the additional iteration is very similar to what you are saying about the intermediate list having some possible negative performance implications.

We can’t update Precompiled.zip because it needs to be built with an OTP version that is compatible with largest number of users and this means using the oldest supported version. The fix needs to be in asdf that either needs to compile Elixir itself on the user machine or use precompiled versions that have been compiled against specific OTP versions. An issue has been opened for this: Consider always building from source · Issue #27 · asdf-vm/asdf-elixir · GitHub.

Thank you @josevalim and Elixir team. Elixir makes me happy during work, and that’s what I value most from a language. You guys actually care about dev UX.

By that reasoning we may as well get rid of Enum.map/2 and Enum.filter/2 too since they can both also be represented with a comprehension.

hmm, I think that I will add this to my library that I’m working on. It will be called ExUtils. I already have some interesting functions implemented, but I still need more time for it.
I wonder if what the elm community does is not a better approach: when someone needs an extra function for a module of the standard library, a separate library with the name of the module and the -extras suffix is created.
For example: Enum → EnumExtras (or we could do Enum.Extras).
Perhaps it would help to have a different git repo for each “Extras” module too. Since you seem to lack the time to get it done, you would most likely become a community bottleneck 
. So if you personally create lots of extras for the List module, you don’t become a bottleneck for those who want to create extras for the Map module.
Example: GitHub - elm-community/maybe-extra at 4.0.0 · GitHub

@svarlet: It’s exactly what I want to do. Whole library will be called ExUtils and module for Enum extras will be called ExUtils.EnumUtils. Currently I have some useful String utils. I’m working on some RFC regular expressions and extended String pattern matching. I will also look for other modules and I will compare them to other languages/frameworks looking for ideas.

@ericmj, @michalmuskala just fixed asdf-elixir so it’s now possible for it to install versions like: 1.5.0-rc.0-otp-20, binaries will now be downloaded from repo.hex.pm as shown on bob’s README. Thanks for your reporting this issue.
