> Is it easier to reason about a 10,000-line-long math proof, or a 10,000-line-long program? I'm not sure that the math is actually easier.

Don't compare them on the basis of familiarity. Making your programming language look mathy is not the point.

I'd offer a different comparison:

Reason about a 10,000-line-long math proof, or a 10,000-line-long math proof in which there are instructions to jump back-and-forth with your pencil, crossing out and updating previously-calculated values in-place.
