Re: Vectors

[David Jeske <jeske@...>]

You certainly can use tags to overload the arithmetic operators. 

I think you should ask yourself the question: Is it more important for
vector accesses to be fast, or transform/operations on the vectors to be
fast. If the latter is true then I would look back a few emails (or I can
dig it up) for an email of mine which explained how to make a C data
structure look like a table to Lua. If the former is true, then just make
a Lua table, change it's tag, and setup some tag handlers to do the
math operations.
