how does one do M:F() calls ?

[Alex Shneyderman]

In Erlang I can do -

M = erlang

F = now

M:F() 

I am trying to figure out how a thing like that can be done in Elixir. Any hints?

iex(1)> m = System

iex(2)> m.tmp_dir()

"/var/folders/pk/r9_ncwsn6qq91bpjbhyxgg400000gn/T/"

iex(3)> f = :"tmp_dir"

iex(4)> m.f()         

** (UndefinedFunctionError) undefined function: System.f/0

    (elixir) System.f()

To call out to Erlang it's :m.f in Elixir it's just m.f

Michael, in his case, they are variables.

Alex, just use apply/3:

apply(System, :tmp_dir, [])

Thanks José, I shouldn't have replied after just skimming the email. Next time I'll read a little closer.
