None that I can think of.

I asked, and Tom seemed a little surprised and (paraphrasing) said you
should be able to (s)tep or (n)ext into eval blocks, but if that isn't
working you could set an explicit (b)reak on the line you want to stop.
Worst case you could add `DB::single = 1` right before in the code, but
that is very seldom necessary.

Perhaps I misunderstood what "handling eval" means.
