That is a huge problem.

Let's say that the class you want to finalize, Target, has a method like 
void foo(SomeClass){}

Let's say that SomeClass is private and in the same module as Target.

You *may* be able to do this with templates. Probably.

You *can never* do this with a string mixin.

Let's say you have another method:
void bar(SomeOtherClass!(int)){}

SomeOtherClass!(int).stringof == "SomeOtherClass". That is also 
guaranteed fail.

What you can do is:
void foo(ParameterTupleOf!(__traits(getVirtualFunctions, Target, 
"foo")[0] u) {; }

Here, the only string you need to mix in is for the identifier.
