why no break N levels, as in other leading languages?

"May", yes. Consider this bit from my TextDB module:
try:
for ORlist in includes:
try:
for filter in ORlist:
for field in curr_fields:
for item in record[field]:
if item.lower().find(filter) >= 0:
raise Found
else:
raise NotFound
except Found:
continue
except NotFound:
continue
else:
result.append(record)
I think it's pretty nifty that I figured out how to use overlapping
exceptions (combined with else) to avoid tracking how many matches there
are in a series of ANDed conditions.
