It works very well in fully debugged applications. In the 99.99% other
applications, advice is to leave the assertions on during production
time so your app will fail fast when a bug pops up (profiling will
point you to the two assertions that needs to be turned off for
Personally, but I'm talking without too much thinking here, I think
support for assertions in Python should be based on generic support
for metaprogramming - there's more than DBC that could benefit from
that (aspect-oriented programming, etcetera).
