A simplified test case:
---
template CtorMixin() {
    this(T)() {}
}
class B {
    mixin CtorMixin!();
}
class C : B {
    this()() {}
}
void main() {
    auto c = new C();
}

I think it is an accepts-invalid code in 2.060 and earlier.

In class NBTFile, implicitly generated default constructor will try to call
super class default constructor. But, in its super class TAG_Compound, template
constructor - which mixed in by _Base_TAG - requires explicit template
parameter to call. Therefore, the generating an implicit constructor in NBTFile
and whole compilation should fail.
