I found out about AliasThis on the IRC, and it's pretty neat.
I've got a suggestion for it however: Assigning a value to a
class/struct which has aliased a member to this would forward
the assignment to that member.
For instance:
----
struct IntPair {
private int _pair;
int left() { return _pair[0]; }
int right() { return _pair[1]; }
}
IntPair a = [1, 2]; // _pair = [1, 2]
IntPair b;
b.left(); //0
b = [3, 4];
b.left(); //3

Thoughts? I think it'd be very useful for defining types that
look and act like built in primitives, but can have arbitrary
methods and operator overloads attached to them.
Thanks to <jA_cOp> for bringing up AliasThis in IRC :-)
Just overload assignment operator for that.
int[2] opBinary(string op)(int[2] rhs) if (op == "=") {
_pair = rhs;
return rhs;
}
