Metatable methods

[Александр Машин <alex.mashin@...>]

Dear all,

Is there a way to find out whether metatable methods __pairs() and 
__ipairs() are invoked by pairs() and ipairs() other than
checking _VERSION (my code will be run in an exotic environment)
or probing, i.e. defining such metamethods for a dummy table and 
checking, if they are actually called?
