Should we add `a * b` for vectors?

This might be a step in the right direction. It doesn't need to 
be full-blown extension methods/partial classes. Just the ability 
to treat operator overloading like free-standing functions (with 
power of UFCS). Something like:

struct Foo
{
     int data;
}

Foo opBinary!(string op)(Foo x, Foo y)
{
     return mixin("x.data" ~ op ~ "y.data");
}

That would mean you could also do something like:
import lubeck : opBinary;
