It's not my mail client, this was my proposed code in which C2 is
defined *outside* of C1, then you inject one or the other (can't decide
for you as it depends on what you're trying to do).
In other words, it's not an indentation error.

I tend to use keyword arguments a lot because it gives me a lot of
freedom. Just a perk: I can do things like change the API and I'd only
have to catch the call, issue a deprecation warning, and then use the
new API instead of having the code be rigid.
