This may be overkill and probably slow, but perhaps most in the spirit
that you're asking.

Hello,
I want to add an item to a list, except if the evaluation of that item
results in an exception.
I could do that like this:
def r(x):
if x > 3:
raise(ValueError)
try:
list.append(r(1))
except:
pass
try:
list.append(r(5))
except:
pass
This looks rather clumbsy t
