As I stated in my post yesterday, I am quite convinced that these
operators ++, **, // will be only used by about 1% of Lua programmers,
and only by specialists
Specialists deserve comfortable programming too :-)
I'd prefer some sort of @+, @-, @/, @%, @//, @^, @= for integer operators.
The integer attribute (symbol "@") may be changed to some other symbol (backslash, dollar).
"x @= y" means "x = floor(y)", it is shorter than "x = y // 1"
