This is probably some variation of some other bug, but it is hard to tell for
me. In the example below there is a recursive instantiation of foo, A and B. It
takes both calls to foo and the pure attribute to make the compiler crash.
Otherwise it prints:
test.d(4): Error: forward reference to inferred return type of function call
foo(A())
test.d(8): Error: template instance test.B!(int) error instantiating
test.d(10):        instantiated from here: foo!()



struct A(T) {}
struct B(T) {
    unittest {
        foo(A!int());
    }
}
auto foo()(A!int base) pure {
    return B!int();
}
auto l = foo(A!int());
