Last time I checked, the "~" character was the standard logical symbol
for "not." At least it was in my statistics class (e.g. "A|~B"). So
really the tilde character makes more sense to me (though I admit my
knowledge about this topic is somewhat limited).

Does anyone have a good reason why "!=" should be used that does not
reference other languages? I think this is an important point since Lua
was designed to allow non-programmers and artists to write scripts,
these people probably haven't been exposed to the "!=" format. Whereas
with the "~=" operator, at least this would be familiar to people who
took logic courses.
