Yes, but ONLY for mathematically dubious inputs. Please don't generalize,
it doesn't help anyone.
I have been working on a patch that will check the arguments of the
function while applying chain
rule and can warn/raise appropriate errors. However, I am planning to do
this in next
revision and after having some feedbacks from its users.

Sure. However, it would be premature to merge this with global "diff" now,
given its a
new implementation and there could be issue which are not yet known. So I
would prefer
to wait couple of release cycles before considering such a move.
