I don't think this will work. Some of the proposed changes are not
restricted to the surface syntax.

On the other hand, I do believe that Lua could benefit from a small
set of quasi-standard types (or object behaviors). Some time ago, I
posted a list (see <http://lua-users.org/lists/lua-l/2010-03/msg00423.html>),
and here it is again:
- mutable byte arrays
- arbitary-precision integers
- I/O handles (multiple different kinds on some platforms)
- UTF-16 strings (mainly for path names on Windows)
- a NULL value for use in SQL and JSON, distinct from nil
- perhaps decimal floating point numbers
Those would come with a stable C API so that C libraries could use
these types, too.
The expectation is that these types would facilitate efficient
communication between libraries from different sources.
Sorry for hijacking your thread, but that's what I thought about when
I saw the subject line.
