Where are the docs?  What operations are allowed?  (For example, do you
allow unary minus - if not, why not?)  Must the operands be the same type?
Can you do operations between a vector and a scalar?  Where are the
testcases for all this (that allowed operations and type combinations
work, and that non-allowed ones don't)?  What happens if a particular
operation isn't supported on particular types on a particular processor -
do you synthesise the operation?
