Pratt
so, I read this. https://dl.acm.org/doi/pdf/10.1145/512927.512931
but I've never done this before, so I have been having trouble getting a vibe.
A point Pratt mentions is that the central problem is that you can't get people to accept a prefix language like this:
print + * 2 3 * 4 5
(assuming + and * act on two elements)
but there are these crazy #lisp people, that if you add overspecified brackets:
(print (+ (* 2 3) (* 4 5)))
Say they will happily read and write, and can understand this expression perfectly.
