Also, some of the standard perumations would also need to do some

($int - $num) would invoke Int-sub[NUM](sv1,sv2,0), which itself would
just fall
through to Num-sub[INT](sv2,sv1,1) -

Experimentation on perl5 says yes.

That is a Language and not an internals issue - Larry will tell us.
But I suspect the answer is that it should "work" without any special
stuff for simple perl5-ish types - because you need to be able to
translate 98% of 98% of perl5 programs.

My original suggestion was that scalar types provide a method that says
how 'big' it is (so complex bigreal real int etc),
and pp_add(), pp_sub() etc use these values to call the method associated
with the biggest operand,

I think this this boils down to 2 important questions, and I'd be interested in
hearing people's opinions of them.
1. Does the Perl 6 language require some explicit syntax and/or semnatics to
handle multiple and user-defined numeric types?
Eg "my type

The "add" op would, in C code, do something like:
