Thank you! However, i was (and am) quite confused that such explicit
evaluation is needed.
I was just playing around with maxima's equations and spotted another
thing that i find inconsistent.
You and John explained that "x==x" returns an equation since the
underlying maxima system does.
So, why does maxima('x')==maxima('x') return True?
And why maxima('x==x') freezes?

Automatic simplification is one thing. But is there an explicit way to
explicitly change an element of the fraction field of QQ[x] into a
canonical form (i.e., two elements are equal iff the canonical forms
are identic)? Note that "simplify" doesn't do it.
Yours
