Even if the simulators are "brittle" and offer "unsure results", I was
thinking - i.e. the .oO(...) notation - that such a test would have
caught when I totally destroyed depcomp.  I'm sure you agree that
having the dependency mode simulator tests wouldn't be bad, if they
just magically appeared and noone had to write it all.
