C++ disallows virtual member templates and attempting to declare one causes a
compile-time error.  D doesn't support them, but it does allow same-named
template functions that would normally be considered virtual.  Worse yet, the
"override" attribute on such functions is ignored.
































Prints:

base
derived

Removing the definitions for fn() in C & E causes a compile-time error for F but
not for D.

At the very least, it would be nice if "override" were not allowed as an
attribute of member template functions and the documentation indicated that such
functions are implicitly final.
