Why Erlang tuple module is controversial?

Question

A similar question was asked Parameterised Modules in Erlang, it is about \"what\". My question is about \"why\"?

Answer 1

There are other issues as well:

• When I write Foo:bar(42) where Foo maybe either just a module name or maybe a tuple module but I don't see the difference. This means I might be calling either bar/1 or bar/2.

• I can call the same function in different ways.

• It can be difficult to relate errors in functions to the call as the arity is different.

And more. I think it is a shame that we didn't get rid of tuple modules when we got rid of parametrised modules. They were originally just a hacky way of implementing parametrised modules.
