Description
Environment
- Elixir & Erlang versions (elixir -v):
Erlang/OTP 19 [erts-8.2] [source] [64-bit] [smp:8:8] [async-threads:10] [hipe] [kernel-poll:false] [dtrace]
Elixir 1.4.0 - Operating system:
OS X El Capitan
Current behavior
iex(1)> f = &List.first/1
&List.first/1
iex(3)> case f do
...(3)> &List.first/1 -> 11
...(3)> end
** (CompileError) iex:4: invalid expression in match
(stdlib) lists.erl:1354: :lists.mapfoldl/3
however the other way works as expected:
iex(3)> case &List.first/1 do
...(3)> f -> 22
...(3)> end
22
Expected behavior
As a first-class citizen, function should work in case
as it works in other pattern matching cases.
iex(3)> case f do
...(3)> &List.first/1 -> 11
...(3)> end
11
