Re: [Haskell-beginners] case statement

      Thank you Brandon.

Well in Erlang you can mix and match patterns with outer scope
variables. It is very handy, I agree. Here is an example.

You can try this code in browser here:
http://tryerl.seriyps.ru/#id=e3f2

% -*- coding: utf8 -*-
-module(main).
-export([main/0]).

main() ->
    check(2),
    check({other,4}).

check(X)->
    A1 = 1,
    A2 = 2,
    case X of
        A1 ->  io:format("A1~n");
        A2 ->  io:format("A2~n");
        {other,X1} -> io:format("~p~n",[X1])
    end.
