ctb macro and BIT_ISCOLLECTABLE

[Dibyendu Majumdar <mobile@...>]

Hi,

Is there a reason why the ctb macro is used instead of ensuring that
the collectible types have the BIT_ISCOLLECTABLE bit set by default?
That is why not:

#define LUA_TTABLE (5|BIT_ISCOLLECTABLE)

Is there a scenario where a value's type could be just LUA_TTABLE
without the collectible flag set?

Thanks and Regards
