How much more expensive would this be than
for f in math.sin, math.cos, math.tan:
squares = (f(x)**2 for x in inputs)
plot(squares)
which would work without reiterability, right? The underlying generator
function could still be created at compile-time and it (or its code object?)
stored in the current function's constants. 'f' is simply an argument to it
when the iterator is instantiated.
