So we can overload on @property-ness?
No.
I.e. this works
struct S
{
@property
float x() { return 1.0f; }
float x() { return 2.0f; }
}
void main()
{
S s;
writefln("%s", s.x); // writes 1.0
writefln("%s", s.x()); // writes 2.0
}
That just looks wrong.
Ok, so you can't have both dynamic properties and dynamic methods with
this. One or the other, your pick.
Seems like an unfortunate limitation.
what a minute, can't you use template conditionals to distinguish? i.e. I
would expect this to work:
struct S
{
@property float opDispatch(string s)() if (s == "x") {return 1.0f;}
float opDispatch(string s)() { return 2.0f;}
}
void main()
{
S s;
writefln("%s", s.x); // 1.0
writefln("%s", s.y()); // 2.0
}
Overloading opDispatch based on the called symbol name should always be
possible, and overloading on parameter types is always possible.
