I've tested some things on Win7 and happen to have an Emacs24 installed
there, so I compiled the latest org-mode.  I got quite a few warnings
that I've never seen before with Emacs23, so I assume this is Emacs24
tightening the screws on some loseness.  I don't remember the exact
warning text, but it was something about top-level forms and global
variables not having a prefix (presumably to keep them in their own
namespace and not step on the toes of other packages).


Regards,
Achim.

AFAIK this is because emacs-24 now supports lexical scope. The use of
name prefixes is used to manage namespace as you mention, but also as
convention used by the byte compiler to help distinguish between uses of
lexically and dynamicly scoped variable bindings.

See the emacs-24 elisp manual for more details, or ask the friednly
folks on the on the emacs devel list.

Yes, there is lots of (boring) work to do in this area to get rid of
those warnings.  

Thanks for bringing this up,
