I completly agree, and wasn't trying to sell Complex for any integral type!
My only suggestion was to use a generic template to determine what operators
were supported by a type, based on your suggestion to use compile-time
interfaces, à la std.range.
I was using BigInt as non-built-in numeric type, the only one available on
Phobos.

But then I thought that the compiler already checks at compile-time that the
operations are possible, so I'm not so certain about the need for such a
template. Maybe as a way to document the code?

Sorry for the noise, I'll let you continue your good work.
