Garbage collection, RAII, dynamic typing, template metaprogramming, macros, type inference, exceptions ... are not "syntactic" features of programming languages. Those are semantic features, that happen to have a syntax.

Reducing programming languages to syntax+isTuringComplete is missing the forest for the trees.

I agree because I think dismissing Coffee++ as just Python-like syntax also seems to ignore semantics. That was the gist of my remark.
