I know I can parametrize template mixin types, but how about mixin
identifiers? This is the code:
----------------------------------------------------------------
mixin template Box(T) {
T val;
}
class Set(A, B) {
mixin Box!A a;
mixin Box!B b;
}
alias Set!(int, int) IntSet;
int main(string[] argv) {
scope auto s = new IntSet();
s.a.val = 3;
}
----------------------------------------------------------------
As you can see, the A and B types can be changed and with them the boxed
values. But they need disambiguation, since they have identically named
members. I know only to hard-code that disambiguation.
I need this because I intend to change (A, B) with a type list
eventually and I need to make operations on the boxed types independent
on the template mixin identifiers (a, b).
This pattern comes from C++ code, where Box(T) would be classes, Set (A,
B, ...) would recursively apply multiple inheritance on the type list.
Then each Box members could be addressed by casting to the correct Box(T).
Any idea if this is possible in D?
Thanks!
