[erlang-questions] Proposal for not allowing tuple calls

Are there any plans to introduce a 'module' type in erlang? That would allow to get rid of that abomination called tuple calls and introduce a correct implementation of parameterized modules. Exactly the same way as lambdas capturing context values were introduced. 
Best wishes,
