Does it beat OO Java classes with students crying ? or months spent on warning kids not to mutate an iterator or else you're gonna cry again ?

Mostly kidding but different paradigms bear different pain points it seems.

Oh and lastly, the let-us-care-not-about-syntax is also an argument at Brown edu (krishnamurti and his team IIRC)

That said, I'd be curious to hear what your students had to say about scheme confusing traits.
