error in tuple matching using variables

Note that it works if you pass the actual tuple itself:

@@@$ bin/ire Reia Interactive Shell (prerelease) Running on Erlang (BEAM) emulator version 5.6.3 [source] [64-bit] [smp:4] [async-threads:0] [kernel-poll:true]

module Retem .. def simple((~number, val)) .. val .. => ~ok Retem.simple((~number, 1)) => 1 v = (~number, 1)
=> (~number,1) Retem.simple(v) exception error: no function clause matching 'Retem':simple({number,1}) in function erl_eval:do_apply/5 in call from reia_erl:erl_funcall/3 in call from 'Eval':exprs/2

Ugh. Stupid formatted. Let's try that again:

$ bin/ire
Reia Interactive Shell (prerelease)
Running on Erlang (BEAM) emulator version 5.6.3 [source] [64-bit] [smp:4] [async-threads:0] [kernel-poll:true]

>> module Retem
..   def simple((~number, val))
..     val
..
=> ~ok
>> Retem.simple((~number, 1))
=> 1
>> v = (~number, 1)      
=> (~number,1)
>> Retem.simple(v)
exception error: no function clause matching 'Retem':simple({number,1})
  in function  erl_eval:do_apply/5
    in call from reia_erl:erl_funcall/3
      in call from 'Eval':exprs/2

Yes, thanks! I've included this piece of code especially to show that it works fine if we are passing the value, not the variable. The second case shows the problem itself. Besides, ticket title speaks for itself.

Note that this problem does not occur in compiled expressions:

>> module Foo
..   def bar
..     val = (~number, 3)
..     baz(val)
..   def baz((~number, val))
..     val
.. 
=> ~ok
>> Foo.bar()
=> 3

It only occurs when the expressions are evaluated because the tuple value bound to the variable is being clobbered.
