Meanwhile, I patched the existing legacy bridge to be garbage

been working with pieces from Gus Mueller's LuaCore and added some

is all intended as a temporary layer on the bridge. The next-gen
bridge at least on Mac should be using Bridge Support (like MacRuby
How much of this is OSX-specific? Will it work with GNUstep, for example
(since I don't have a Mac handy...)
Also, how much introspection can you do on a bridged object? Do you see
them simply as opaque Lua objects with method calls peered over to
Objective C, or does the full Objective C class hierarchy appear in Lua,
which you can then add classes to, etc?
We still lack a good object model. From the one minute I've seen of
Objective Lua, it is very compelling. Is the translation done all
through Lua (no C)? If so, this reminds me a lot of Objective-J and
application framework called Cappuccino.
About a minute is all it's worth; right now the Objective Lua 'compiler'
is an almost trivial syntax hack. The object model is a traditional
metatable-based Lua OO system. The only thing slightly interesting about
it is that it supports class methods. In fact, it's currently all wrong,
and I need to rewrite it. I think I've got a fairly simple design that
can support categories.
I didn't know about Objective J; it's rather interesting, and very much
the same sort of thing. In fact, I might steal some of their syntax.
There's been a surprising amount of interest. (The reddit link didn't
help...) In the past 24 hours that one page alone has had 3300 hits. I
usually get about 2000 hits a month *on my entire website*! Admittedly,
only 36 actual code downloads, but it's certainly striking a chord with
people. Maybe it *would* be worth doing properly...
