alias this is for implicit type conversions, which can be achieved
explicitly as well. Given the following old code:
class C {
int* result;
alias result this;
}
void foo(int*) {
}
auto main() {
auto c = new C();
// Implicit type conversion from C to int*:
foo(c);
}
One can use a member function instead:
class C {
int* result;
auto asIntPtr() {
return result;
}
}
void foo(int*) {
}
auto main() {
auto c = new C();
// The same type conversion is now explicit:
foo(c.asIntPtr);
}
