Alexandre Erwin Ittner a écrit :
May I ask you (and others) why you need boolean operators in Lua? (This
is not a rhetorical question. I really want to know what uses boolean
operators may have in Lua.)

Some time ago, a wrote some bindings to libraries that uses bitwise OR to
combine options. So, people using something like
  xxx_type *hl xxx_open("~/", XXX_CREATE | XXX_SOMETHING_ELSE);

will not be confused when porting code to Lua:
   local hl ="~/", xxx.CREATE + xxx.SOMETHING_ELSE)

Which of course is risky if you combine options with same bit set (eg., still with Windows styles, some styles are just aggregates of other styles).
