FWIW there's the possibility that even without a
subexpression syntax, some Python implementations
would detect the duplication of x*x and optimize that
for you.  It would have to know that x*x had no side
effects, which I think is a safe assumption even in a
dynamic language like Python.

I know the CPython implementation does do some types
of optimizations (peephole, etc.), but I'm not expert
enough to know whether this kind of optimization would
be detected.
