Re: Is there a C API equivalent to the new # operator for tables?

["Jose Luis Hidalgo" <joseluis.hidalgo@...>]

Of course it can exists, but... The code will be similar to the one I
posted, look that you need to call a function, What if that function
call fails? What if the "__len" is a pice of code tha does something
invalid? IMHO calls like lua_getobjlen are supposed to not fail...

Its very easy to generalize the function to call whatever other
metamethod, I'd rather lua API as it is, simple, small and very easy
to extend... I don't see any necessity of making more complex the lua
API for such easy-to-implement-by-my-own calls... just an opinion :)
