The 'abs' builtin does return the magnitude of a vector - I checked
before posting the email. It doesn't work for tuples, only visual's
vector types. I'd actually forgotten about the 'mag' function, but I
assume that _would_ work for tuples, as it'd auto-convert them into
vectors like all the other visual functions.
