Re: Bitflags

[Asko Kauppi <asko.kauppi@...>]

I'm using BitAnd(a,b,...) etc. for SDL interface. Not nice but..

For me, the speed issue is not so decisive as the fact that any such 
function name usage clubbers the code and makes it harder to read. Yes, 
I do miss the '&', '|' etc. operators in Lua.  But one can't have all?
