Yet only 2 of them can be overloaded.

It's cool that Lua has 4 forms of negation tho.
As I understand "-" is for general numbers, "~" for integer numbers,
"not" for general logic and "~=" for equivalence logic. From them only
"~=" may be dropped and reformulated as "not ==".

What, "~true" isn't a good replacement for "not true"? A boolean has a single bit so bitwise negation on booleans makes sense...

Also you may count table.insert(), t[#t + 1], "+" and ".." as addition.
