Okay, Im trying to wrap my head around how i can return a
reference from a class.
Lets say I have some class Foo that stores a struct Bar that
stores many bytes.
In C, i would have a function
const Bar & getBar(){return bar;}
In code, i could get a (const) reference to bar using
const Bar & v = foo.getBar();
or i may copy it, if i need to use it for something else
Bar v = foo.getBar();
How can i do the same in D? The manuals aren't crystal clear on
this matter. Using in in parameter lists will give me a const
reference, so that i avoid input copying, if I understand
correctly.
But i want get const aliases to structs, and if i should pass
that alias into a variable storing a struct, then i would want
the copy semantics.
