The point is the break destination.

|   p hash
|   break if hash['i'] == 5

|# this produces an error...
|obj.fetch(&data_loader)

The destination of a break in the data_loader is the continuation to
the "proc", which is already passed through at the point of
"obj.fetch".  Use catch/throw for dynamic exit.
