Are there container templates that one can mixin to classes that
give them container behavior?
e.g.,
instead of
class A
{
Array!int x;
}
I want
class A
{
mixin Array!int;
}
so that I can do something like a.Add(3) instead of a.x.Add(3).
One solution is to use alias this.
class A
{
Array!int x;
alias x this;
}
Then you can do a.Add(3) and the method call will be "rewritten"
(I don't know if it's *actually* rewritten) as a.x.Add(3).
myints nor myfloats need to be actual elements of the class. In
fact, in this case it might be ok to override them, e.g.,
a.add(1) and a.add(5f) above.
This throws a wrench into the above solution, as you can
currently only have 1 alias this. However, your idea of inner
classes would work, I think.
