Function types being converted to dynamic types

[paulsgcross]

Hxcpp transforms function types into dynamics (shown here). Surely it should be converted into a C++ callback in the traditional sense or Callable?

Using HxScout showed a large object footprint when using function types for callbacks, i.e. var func : Float -> Void; and then calling func(3.0). A 'Float' object was created each frame which then needed to be garbage collected. This incurs a big cost at runtime because any time a callback is required, the garbage collector is clearing up potentially thousands of objects that have been seemingly generated for no reason.

I think this is legit issue

I'm pretty sure this is a duplicate, but I can't immediately find the issue I'm thinking of, so we can let this sit here if you like.
