Exposing getters of nested structs from the top level struct

[fa993]

Consider 2 structs as so

struct A {
a: T1,
b: B,
}

struct B {
c: T3,
d: T4
}

Could we add an attribute that could maybe expose the getters of B as if they were getters of A?

So instead of invoking a.b().c(), one could invoke a.c() directly.

I am happy to contribute code for this, as well as discuss possible design issues as well.

Thank you.
