I do it with all the separate variables mainly for performance. If I
had the headers in a dict, I'd be looking up a string in a list of
strings (the keys of the dict) everytime I check for a header. Not
that that's going to take more that 0.1 seconds, but the program is
still small and simple. As it gets bigger, more features are gonna
slow things down.

- Have you measured the difference in performance?

- Are you aware that attribute access is implemented as string lookup
in a dictionary?

i.e. when you write foo.bar, the interpreter looks for 'bar' in
foo.__dict__, and if it doesn't find it, then proceeds to look in
type(foo).__dict__. So in your code, if a header (with manager rhm)
has no 'allow' field and you do:

rhm.Allow

the interpreter looks up *two* dictionaries (rhm.__dict__ then
RequestHeadersManager.__dict__).
