Review comment:
I originally pointed this out as well (just deleted the comment
yesterday). The reason I thought this isn't necessary is because `and` and `or`
as prefix functions take arbitrarily many arguments (opposed to the postfix
ones which are unary). However, `not` is always unary, and a prefix version of
it thus doesn't seem as useful. Happy to add it if you still feel otherwise,
though.
