I think it is a good idea to put "substitute" (the synonym for quote)
around the call objects when deparsing. Splus restores correctly with
the calls encapsulated in a substitute(...), as does R.
I suppose I should submit a bug report to MathSoft and ask them to fix
thier deparse as well...

If R is fixed, I can create a "dump.correct" for S which calls perl
directly to fix things up. Then dump/restore will work everywhere.
BTW, can we have
restore _ function(...) source(...)
in base, so that the a user looking for restore doesn't have to figure out
that source can be used instead?
