Subject: [Caml-list] Some things are more equal than others

Silly newbie question coming up...
What's the difference between (=) and (==)?
I know that this is almost certainly a case of RTFM, but I can't seem to find
the right place. 6.7.4 mentions "structural" and "physical" equality, but
doesn't define either.
My guess is that "physical" equality is "are these the same object", and
structural equality is "are these objects equivelent". Hence:
# "Jim"=="Jim";;
- : bool = false
# "Jim"="Jim";;
- : bool = true€
I thought I'd better check I'm guessing right, or I will almost certainly
fall over this sometime in the future. :)
TIA,
Jim
