Cosmo's development tree (available from LuaRocks repository
http://luarocks.org/repositories/rocks-cvs has the $(name)_new syntax.
The syntax is actually $(<exp>), where <exp> is a Lua expression
(minus functions) evaluated in the current environment.

You can see a log of commits at http://github.com/mascarenhas/cosmo.
