Re: is "__metatable" an event similar to "__gc" and "__tostring" or is it a convention?

I added the "metatable" field in the "gdbm" table to be get access in Lua
to the metatable of GDBM objects in Lua. It was purely for convenience, because
some things are easier to write in Lua, specially during the test phase.

The code
	gdbm.metatable.__index=gdbm
could have just as easily been written in C, as done in
