I never understood why a lack of tooling would be a serious problem for a language used for teaching FP.

It's a tough sell if the language has no hope of industry adoption. Also tough to use a language, especially one with type inference, without editor support.

Most people in my SML class seemed to have no problem with either of those.

Maybe some classes are just that good. A lot aren't, I'm guessing, and you would want to at least take away something you could use in the real world from them.
