Metalua 0.4 released

Metalua 0.4 has been released. Unfortunately it hasn't got a very convincing support for macro hygiene yet, but there's just too much work and experimentation left on this subject. If you're interested you're welcome to dig in the extension H and its runtime, and ask questions on the mailing list!

Metalua 0.4 rc2

Look at the README.TXT file for details on what's new. There probably are some issues left; I've already received reports that the Pluto integration doesn't work on some systems. If you have that issue, set the environment variable LUA_NOSPRINGS to true, and you should be fine. If you have a problem, either this one or another one, please take the time to report it.
