YES! i prefer "^" but another alternative is "**" (like Ruby)

again, yes!
but i agree with what's been said about this "|" symbol before, it's
just too ambiguous looking.
alternatives: compare could be "~", but "==" is better
and_bits ---> "&and"
or_bits ---> "&or"
xor_bits ---> "&xor"

the only problem with modulo is that it's sometimes NOT a well defined
function. go to Dr. Math and you'll see that there are several
definitions of modulo
(http://mathforum.org/library/drmath/view/52343.html).
however, i agree with the missing operator sentiment (and i like the "%"
symbol).
i hereby respectfully request Rob to include the function as a built-in.
all Rob has to do is define what the parameters of his built-in function
are if they aren't _standard_.

once again, very good thinking. to combine the divide and floor would
certainly get my attention.

I meant equal() become ==
if ("this" == "this") then -- TRUE
puts(1, "TRUE\n")
end if

oh, another alternative could be
and_bits ---> @and
or_bits ---> @or
xor_bits ---> @xor
