--- Comment #1 from alexandru.ermic...@gmail.com ---
This is not the only case, here is another case of wrong selection:
--
class Mquartz(T, Z) {
Z pass(T component) const {
"Mutable pass".writeln;
return component.z;
}
const(Z) pass(const T component) const {
"Const pass".writeln;
return component.z;
}
const(Z) pass(immutable T component) const {
"Immutable pass".writeln;
return component.z;
}
const(Z) pass(inout T component) const {
"Inout pass".writeln;
return component.z;
}
}
struct V {
int z;
}
void main() {
auto m = new Mquartz!(V, typeof(V.z));
// V v = V(21);
// writeln(m.pass(v));
writeln(m.pass(V(20)));
writeln(m.pass(const(V)(20)));
writeln(m.pass(immutable(V)(20)));
writeln(m.pass(inout(V)(20)));
}
-
Current logic will select only const version with const argument instead of
selecting right ones:
-
Const pass
20
Const pass
20
Const pass
20
Const pass
20
-
The overload selection logic works as expected only if m is const, then
response will as expected:
-
Mutable pass
20
Const pass
20
Immutable pass
20
Inout pass
20
