Lua on MacOSX uses either the dyld API or the usual Unix dlopen/dlsym
mantra in order to load modules. Both sets of APIs do directly load the
binary itself. The APIs which do load bundles are from the Foundation
(and maybe are also available from CoreFoundation) library, more
exactly by means of the NSBundle Objective-C class. Using NSBundle is
more suited for loading stuff containing Objective-C code (AFAIK),and
it would add more compile, link and run-time dependencies to Lua. I
think the current scheme is good, in fact most Unix apps ported to
MacOS X do simply the same as Lua, and at least Apache, Python, Ruby,
Perl and some other do open the binaries directly instead of using
bundles =)
