Do you have to use the variadic thing?
It is easy to do with template variadic or with just regular
arrays of interfaces/base classes.
I just wanna check if a compile_time _argument[0] is a
descendant of a class or not.
_arguments is a compile time construct, it is a run time thing.
I kinda suspect what you really want to write is
foo(T...)(T args) { }
and then you can do `static if(is(arg[0] : A))` to catch both A
and B.
Your approach for the typeinfo thing at runtime was close though,
just it isn't `next` (that's used for like immutable(A), where
next is A), but `base`.
http://dpldocs.info/experimental-docs/object.TypeInfo_Class.html
but with the compile time list foo(T...)(T args), there's no need
to do typeid/typeinfo at all.
