Well, pigment functions don't really return vectors, they return colors.
Same thing, I know, but with a different number of dimensions.

So I assume you're proposing some sort of syntax like:

#declare myvectorfunction = vfunction {
function{...}
function{...}
function{...}
}

#declare myothervectorfunction = vfunction(a,b,c,d){myvectorfunction(a,b) +
myvectorfunction(c,d)}

sorta like that? That would be quite difficult to implement, I'd think...
