Summary
The limit of a derivatives' quotient that grew past GrewTooMuch(AngouriMath.Entity,AngouriMath.Entity), read term by term at a finite
destination without another step of the rule: each term has a finite value at the point, or is a product of
factors with finite non-zero values there and a negative power of the variable's distance to it, a pole whose
sign the side decides. Poles of one sign are that infinity; poles of both signs, or anything else, are
null .

Remarks
(sqrt(x) - erf(x)) / x at 0 from the right steps to 1/2 * x^(-1/2) - 2 / sqrt(pi) * e^(-x^2), which is +oo
there and has no value at the point, so it was left unevaluated where 2.6.0 answered +oo, and so was
floor(sqrt(x) - erf(x)), whose sign is read from that slope. Asking the grown quotient's limit with the rule
kept out of it answers the same, but the descent it runs took seconds on the quotients that grow the most,
and thirty on one of them. Reading the terms costs a substitution each.
