Every time I'm trying to use alias this (which looks like a nice
feature, on paper), I end up with problems. This is the most recent one
(dmd v2.049):
------
struct Foo {}
class Bar {
Foo foo_;
alias foo_ this;
}
void main() {
auto a = new Bar;
auto b = a;
a = null; // fails -- Error: cannot implicitly convert expression
(null) of type void* to Foo
}
------
There are plenty of 'alias this' issues in Bugzilla, but I cannot find
this particular problem there. So is this a bug or feature? The language
spec does not help do decide...
