What does this mean for the further development of LuaTeX?
I would guess that the fourth stage, as defined on LuaTeX's
homepage, is now finished. Still:
- Apart from integrating MetaPost and the TODO list in the
manual, is LuaTeX feature-complete?
- Can the Lua interface be considered as being (more or less)
- What is planned between 2008 and 2010?

This is a really, really great change from the original TeX,
- "--" does not insert a discretionary (well, if \exhyphenchar
is set to 0).
- \hyphenation can contain complex discretionaries, thus allowing
automatic changes such as backen => bak-ken ("to bake").

I'm afraid to ask: What about font expansion? ;-)
> Have fun,
I will. I guess I will dump eTeX as the required engine for my
private format and use LuaTeX all the way. No more active characters
for input and output encoding, better key-value processing ...
Well, as soon as I have figured out how to correctly load OpenType
fonts ... incidentally, that is an place the manual could use some
work: Section 4.12.2 explains how to get a metrics table from an
OpenType font -- but now, what this metrics table contains. That
makes it quite difficult to convert it to a tfm font table.
