I’m curious if anyone would be interesting in giving and trying an occasional coding challenge (perhaps a new tag or category could be made if it gets popular). These would not be ones like Exercism has or so, but strictly challenges to try to solve language-specific tasks that you may never run across in real-life. Let’s do a simple task as an example:
Force non-equality - runtime
Given this code:
defmodule Testing do
def f() do
# Put 1-expression
end
def test() do
false = ( f() == f() )
true
end
end
Fill in the # Put 1-expression here with code to make the test pass where calling Testing.test() returns true.

:erlang.monotonic_timeOvermindDL1
Yep yep.
There is still a much shorter way, without calling into
:erlangtoo, what is it? ^.^JEG2
System.unique_integergregvaughn
make_refbbense
fn x → x end
Not sure this isn’t more or less make_ref when all is said and done.

This was indeed the shortest that I could come up with when I posted it too.
Ah, I’d not thought of that one but I’d bet it would work too!
Ditto too.
There are still other simple ones too that I can think of. ^.^

If we’re golfing this for the fewest characters. and don’t mind abusing syntax, I have a 4 character solution
& &1props to @bbense for the idea
OvermindDL1
Oh that is brilliant! ^.^

When I tried that one yesterday (OTP 19.2, Elixir 1.4.0) I got a match error, so that doesn’t work.

This code challenge is making me have impure thoughts.
