Is this a known bug, or should I report it? If you can't find it searching on bugzilla, report it. - Jonathan M Davis https://issues.dlang.org/show_bug.cgi?id=18646

recursive template expansion: Why does this not compile?
The following code does not compile:
void main() {}
class SuperClass {}
class TemplatedClass(T : SuperClass) {}
class A : SuperClass {
alias T = TemplatedClass!B;
}
class B : SuperClass {
alias T = TemplatedClass!C;
}
class C : SuperClass {}
It gives the error:
test.d(12): Error: class `test.TemplatedClass(T : SuperClass)`
recursive template expansion
test.d(12):while looking for match for
TemplatedClass!(C)
The aliases do not have to be aliases, as long as there is some
reference to the class (e.g. method and variable declarations
also work). What exactly is the reason for this error?
