done.  what about hypot? 
https://www.khronos.org/registry/spir-v/specs/unified1/OpenCL.ExtendedInstructionSet.100.html

"Result Type, x and y must be floating-point or vector(2,3,4,8,16) of
floating-point values."

do they mean x must be a vector and y must be a vector, and the result is:
map(hypot, zip(x, y))

or do they mean... no it's definitely not sqrt(x^2+y^2+z^2+w^2) is it.

hypot would be another separate funct5, have to be careful not to add too
many of those.
