Hmmm. Did I imply I think tracebacks should be shipped to the user? :)

What I meant was that we could use Grouch to raise exceptions which we
handled in our user interface code. Something like this:

def __setattr__(self, name, value):
	_some_grouch_checktype(name, value)
	# do the attribution

on Domain classes. And

def foo_entry_updated(self, entry, *args):
	try:
		domain.foo = entry.get_text()
	except ValueError:
		self.win.statusbar.warn("Data b0rked, should be numeric!")
		entry.select_region(0,entry.get_size())

How does that look? Non-modal output, too :)

This could be done in a custom _set_foo() method too, if you don't like
the setattr hack.

Does this sound insane?

Take care,
