Is it possible to get types or aliases of all constructors of a class

No.

__traits has some random functionality in this regard. It has a command 
getVirtualFunctions which only returns virtual overloads. By "virtual", 
we mean "appears in vtbl". So any non-private, non-static overload will 
show up.

Constructors do not appear in any object vtbl. It would be kind of odd 
if they did.

There's a patch to add getOverloads to __traits. It would do what you 
want. But I doubt it works on DMD >2.020.

Yeah, I know about limitations of __traits. And I don't understand why
virtual functions are special-cased. If it is a temporary hack then I
don't understand why it is in the specification.

That is very bad. I hoped for some clever workaround. Really don't
want to rely on a patched compiler. Probably, will have to wait
another couple of years.
