exceptions

[Aleksei Guzev]

what one should d when he wants smth like this:

def f(d,s,e):
	for i in range(s,e):
		print d[i]

D={1:'blah1', 2:'blah2', 3:'blah3', 7:'blah7', 10:'blah10'}

try: f(D, 1, 30)
except KeyError(key):
	D[key]='blah%d'%key
	RESUME

It's a simple example. Assume f(d,s,e) is defined by another programmer deep
in a module.
It seems to be not a good idea to provide f with a procedural object as an
argument for every exception... Because those programmer SHOULD NOT know
anything of the dictionary I provide. If one defines an object then he
should handle everything concerned with it. This shortens the code and
increases speed.
