Mix does warn about it when you try to call a function from a non-existent module:
$ mix compile Compiling 1 file (.ex) warning: function This.Module.Does.Not.Exist.foo/0 is undefined (module This.Module.Does.Not.Exist is not available) It does so because `mix xref` runs automatically on each compilation. The base Elixir compiler doesn't perform such checks.
