I believe I wrote about them recently.
I meant *bitwise* boolean operators, not *logical* boolean operators.
I don't miss the || && !, I am happy with or and not, not as verbose as 
some people think, and clearer to newbies.
But I miss the | & ^ << >>
I am aware of limitations with a native float number type, but I find 
them easier to use than functions calls.
They are necessary to implement some algorithms (OK, better do them in 
C, but sometime I like to use only the native interpreter).
And when calling some external functions (DLL, WinAPI), either via FFI 
or appropriate wrapper, we sometime need to combine options (Windows 
styles, for example).
Of course, if there is "an appropriate wrapper", it could accept a table 
of options instead, or some other Lua-like solution, but habits can be 
hard to break... :-)
