Template functions cannot be virtual, and it's invalid to override a
non-virtual function.

Which version of the compiler are you using?  I just tested on the
latest dmd git HEAD, and it (correctly) tells me that it's illegal to
override a non-virtual function.  I'm surprised you got your code to
compile at all.
