(I hope I get the OO terminology right.) If I want to tell a table t to be
an instance of a class c, it seems that there are many choices. What are
the pros and cons of each of these, for example:
t.__index = c
or, after making c the target of its own metatable's __index in either of
the above two ways, this:
The first seems the most visibly self-documenting; the second seems the
purest (but needs another table for every instance); the third seems to be
a bit of both.
What does the received wisdom of the list say?
