> Do I want to deal with being blocked due to not understanding how to use the less understood features of racket such as continuations, syntax-parse/syntax-case macros, units/signatures I don't know much about scheme or racket, but am aware that continuations is one of its distinguishing features. I've seen people praising syntax-case as a great take on macros. I've never heard of units/signatures, though. I know this was supposed to be a rant, but I wonder what drew the author to want to use scheme/racket in the first place?
