I mentioned this in #beginners, but I’ll just throw it out here. I wouldn’t be surprised if a well written book on Racket macrology does more to lower barriers than a new syntax. At least for barriers to macros/LOP as opposed to “normal” Racket coding. “Racket Metaprogramming” or “The Little Macrologist”.

As an example: https://www.amazon.com/Metaprogramming-Ruby-Program-Like-Facets/dp/1941222129/ref=sr_1_1?crid=1LXFQ8C5J1FQB&keywords=ruby+metaprogramming&qid=1566352501&s=gateway&sprefix=ruby+metap%2Caps%2C140&sr=8-1

we can always do both :p
