Does anyone know of a good way to rewrite a definition wrt. other
axioms? For example, given:
a1: "ALL x. f x = g x + h x"
a2: "ALL x. g x = m x * n x"
I'm trying to get a new axiom:
ax1': "ALL x. f x = (m x * n x) + h x", i.e. rewriting a1 using a2. Is
there already an existing mechanism that does this? Otherwise, what is
the best angle to approach this?
