Really?
To write a statement   "a and b or c"  when you in fact want "if a is 
true then use b otherwise c" was one of the weirdest things I've ever 
seen so far.

It works, but is very far from being obvious and "human readable".
I think, that Lua has a quite clear syntax in general, but this 
construct is the exception from the general case and the term "hack" 
describes it very well.

The point is that keywords like and/or that are usually used (and I'd 
say by 99% of all programmers seen as) "operations that use conditions 
and result in other conditions" are here really misused to not return 
booleans but other types.

An expression " a ? b : c " where it's explizitly defined and clear what 
happens and what the result is would be way clearer...

(... at least in my opinion.)
