This is an elegant and attractive syntax proposal. I am
mildly concerned, though, about the fact that \context will
be used with very different meaning with respect to the
internals (and thus to user Scheme code) depending on whether
it's inside or outside -- unless one manages to rework output
defs, context defs and context mods in a way that makes it work
equivalently inside or outside (a refactoring is probably
desirable independently). Anyway, I think the syntax discussion
can be had on the day someone comes up with an implementation.

Best,
Jean
