That's fair. My remark was a bit of a tangent, borne of frustration over years of trying to read papers relevant to my interests where the juicy bits are all written in math notation and therefore inaccessible. I have to go track down some open-source implementation of the idea and read that to understand what the paper is trying to say - any programming language at all, even one I've never seen before, will be easier to understand than the original symboldegook.

I can imagine that it's a much different situation with array languages, where the notation is actually learnable, because it is defined and documented.
