The (logistical) issue with this is that e.g., the following is disallowed:

```d
void foo(T...,int x)(){}
```

This gets back to the issue of name mangling, because I think there is 
no way to distinguish an instantiation where the last template parameter 
goes to `T...` and an instantiation where the last template parameter 
goes to `x`.

Of course, this introduces many other issues unrelated to `enum` 
parameters, e.g., I think you cannot have a (non-nested) template 
accepting multiple delegate types with different but variadic parameter 
lists.

So in general, some thought will have to be put into how to support IFTI.
