Remove need of calling constructor on complex structs

[vitreo12]

struct A:
    a

struct B:
    a A

init:
    b = B()  #this should be enough, instead of B(A())

[vitreo12]

This perhaps requires removing the objects as ptr to something, and instead letting them be just normal nim's object types. They could be inheriting from a common OmniStruct object that would help when parsing def arguments, in order to still allow this:

struct A:
    a

def set_value(a A, val):
    a.a = val

init:
   a A = A()
   a.set_value(0.5)

What about Data though?

[vitreo12]

Should Data look at all the entries of each struct recursively and call the standard constructor, initializing all Datas along the way? What size should those Datas have though? Perhaps I can come up with a way of using this syntax ONLY for top-level Datas, meaning: Datas that do not contain structwith other Datas
