Be aware that any further arithmetic with the results of
unsimplified_plus may not be fully simplified. For example,
f(-3/2)+f(3/2) => 1 - 2 + 1, not zero.

Though two single quotes work in this case, more generally if you want
an expression resimplified, you should use expand(expr,1,1). You may
find it convenient to define resimplify(expr):=expand(expr,1,1)$
