It could be confusing if only part of the community used these

Hmm, says the ldoc author/maintainer.  I agree that documentation is
good, but I hate to expect it.  I like function names that document
their use more than documentation that is well written.  If I were a
third-party I'd say we both have valid points here.

I could see things like 'local a??????? = 3' being annoying.  I think
the benefit over the eyesore would be knowing that an identifier for a
non-function is meant to be a boolean.
