Right.  The idea is that you can catch the exception and resume it, in
which case execution continues from the point that the resumable
exception was _raised_.  The exception, when caught, can still be
reraised (and another catcher resuming it will still cause it to resume
from the original point it was raised).  If the exception is not caught,
then it acts as a normal exception and halts the program with a stack
trace.
