But none of the currently proposed exception handling/reporting mechanisms
support any sort of "resume" or "retry" functionality... they just
extricate you from the current code path, and take you to a different place
in some equal or higher code path. Now it would be possible to manually
code the retry in some circumstances, for some errors. However due to the
potential for side effects in the invoking expression, it may not be
possible to do that in general, without language support for "resume" or
"retry" functionality.
