I'm slightly surprised that Rust has implemented the Default trait for booleans: https://doc.rust-lang.org/src/core/default.rs.html#205 The default is false, but it feels very arbitrary. Maybe it makes more sense next to integers, where the default value is 0.

Integers in Emacs Lisp are now arbitrary size, not just 32/64-bit!

Another interesting aspect of OCaml syntax: [1,2,3] is equivalent to [(1,2,3)]. A list of integers is [1;2;3]. This is one of those cases where familiarity with the syntax of other languages can actually make life harder! [1,2,3] doesn't look wrong and is syntactically valid.
