I have written matrix manipulation commands on top of Lua
and I would like to have them be as Matlab like as possible.
Is it possible to somehow have Lua read the syntax


and have that passed to the gettable tag method (or settable?)
So far I have done this:


because it will pass a single object (the table) but not multiple
objects as in x[-5,5].  The reason I want to use this syntax is that
because there is both a gettable and settable tag method I can
use the same syntax for assigning and reading a location.  Does
creating the table for each access of the element slow down Lua

Thank you
