Interesting syntax: all the "let" bindings end with "in", eg

    let comparison =
      (0 == 0, 0 < 1, 1 <= 1, 2 > 1, 1 >= 1) 
    in
Anyone know why "in" keyword?

The bindings are only valid for the expression following in.

Haskell does the same thing.

this is the syntax for variable binding in ocaml.

Hazel appears to be written in ocaml and mentions being "ml-like" on the site
