I meant to talk about generativity of term-formation operations, not
For example, in OpenTheory if you use the const command twice on the same
name, and then constTerm with the same type on the two resulting consts,
the two resulting terms will not be alpha equivalent. This effectively
forces you to put the constTerm into the dictionary as soon as you create
it, so you can reuse the same one.
