I have no idea. Everything? What's the downside of protecting a
macro?
sometimes you want it to be expandable
\unexpanded\def\blabla{\handle{blabla}}
will not expand even if \handle is expandable (could be a problem in for
instance fallbacks for pdf bookmarks and such)
\def\blabla{\handle{blabla}}
now one can overload \handle, and \handle can be protected if needed

Uh-uh. The problem is clear: \inlinemath tries (in the definition of
\inlinemath@) to expand the formula (in the sense of TeX macro
expansion). \longrightarrow cum suis are, however, not expandable in
ConTeXt.
Now, I do believe the xdef is a bug in nath, but the following
workaround does work:
\protected\def\longrightarrow{\relbar\joinrel\rightarrow}
Hans, do you have a command that sort of changes an existing
definition as if \protected had been used in the first place?
regards,
Christopher

Yes, I'd though of that, I justwanted to know if there is some higher
level version already existing.

My guess is that the expansion of \mathstrut, being \vphantom(, is being
misinterpreted as a delimiter (as '(' is active in nath), but that's
just a layman's guess.
Bingo. In nath this is now fixed by letting \mathstrut use |
instead of (.
:-)
I'll try to get the new amsl and nath modules out today.
Thanks, great work.
I don't want to rain on your parade, but I just found another bug:
\usemodule[nath]

\stoptext
gives

which seems a bit more difficult to fix. I can't do it anyway,
