Hello,

I use ABI-aware Lua code to let me poke around in simple C data structures
without the need for generated wrapper code.  (The initial description of
this was posted as "podlib vaporware" in June 2001.  I extended that idea to
support std::string and something close to std::vector in addition to
built-in types.)

Anyway my library takes an ABI definition as input, and I expect other such
libraries do the same.  Having the C++ standard ABI wouldn't really affect
much except making configuration easier.

Even with the standard ABI, (I think) there are still things that are
implementation-dependent such as the layout of C arrays whose element type
has a destructor.
