It's unfortunate IMO that Lua didn't just adopt BitOp and its semantics. The different decisions made by the core Lua developers did not seem compelling to me.

It's unfortunate IMO that Lua didn't just adopt BitOp and its semantics. The different decisions made by the core Lua developers did not seem compelling to me. For example, one of the differences is that you can shift by a negative number with Lua (making the shift go in the opposite direction). Who ever needs to do that? This was all discussed at length on the lists, I don't have a link handy though.
