Tuples Mapping

Tuples are defined as primitive data types in Hamler and compiled to Erlang tuples.

The differences from Erlang are as below:

Tuples in Hamler are enclosed within parentheses, while Tuples in Erlang are enclosed in braces.
The maximum length of Tuples in Hamler is 7, while there is no limit in Erlang.

Tuples in Hamler:

(1, "a", true)
(1, "a")
(:error, "Reason")

-- fst, snd
fst (1, 'a') :: Integer -- 1
snd (1, 'a') :: Char    -- 'a'

Tuples in Erlang:

{1, "a", true}
{1, "a"}

{error, "Reason"}
