"Before you leave, please know: I’m hedged either way. LOP and Racket have been an incredible force multiplier on my programming productivity"
Well, wouldn't we expect that the author of a particular programming language to be mad productive in it because, you know, they designed all the mental models and assumptions that are baked into it?
You would never once stumble on syntactic ambuigity because, to you, there is no ambuigity...or perhaps there is but you slyly added that bit just to fuck with programmers heads...or who knows the reason.
I'm just postulating that for an author to boast about their productivity with the language they designed is somewhat self-serving.
