I could go for either of those approaches, if applied uniformly, and
actually Greg's suggestion sounds a bit better: it seems more likely
to preserve some readability in deeply nested constructs.
With either approach you need to ask where the limit value is going
to come from. Is it OK to just hard-wire a magic number, or do we
need to expose a knob somewhere?
