As pointed out by Stavros, the '' operator causes a substitution
when the function body is parsed, not at run time.
I find that replacing the assignment to f in myScaled
with

f : buildq ([v, h], lambda (v, h))

does yield scaled_u the same as the final h.

buildq is a parallel substitution function which does not evaluate
the expression to be substituted into.
