Redirect?  So that, for example:
    a=f()
would NOT actually set a, but rather (leave it as before? or what
else?) and instead place f()'s return value somewhere else?  That
seems like a tall order to me, and I don't understand how it would
help -- surely you're using the value of a in later code, so if it does
not get set this will affect your code's logic...?
