I realize that that's a simplified example but really, isn't this just
as easy?

try:
   Some code
# except Some_Exception:
   # Commented code for when I am debugging <Some code>

If your code block really is one line is "pass #" really so much more
of a hardship than "#"?  If it is a large block use "pass #@#" which is
easy to remove with a search and replace.

In any case, the rule about premature optimization for programs can
probably be applied to developers too.  Is saving a "pass" once in a
while really where you need to focus your debugging efforts?
