I could see an issue with something like this:
try:
# do a call that can fail with TypeError under certain conditions
do_call()
except TypeError:
# assume that the call failed
If you now make an error in do_call(), e.g. calling a function with too
many arguments, your code always assumes that the call failed.
Sure, it should be caught by unit testing, but it needs debugging anyway.
