I think getting rid of division is a really great idea, partially 
defined functions are just a terrible annoyance. Division should be 
allowed by units (1, -1) at most.

I would like to suggest that we also abolish squaring. Non-injective 
functions are an annoyance, too. Torbjörn, could GMP's multiply 
functions check if the two operands are identical and abort if they are?
