> CPython does not lexically scope function bodies 

I'm not sure what you mean by lexically scoped here, since in my
opinion Python functions *are* lexically scoped -- however the scopes
don't nest like they do in Pascal etc.  (The opposite of lexical
scoping is dynamic scoping, which is emphatically *not* used in Python
-- variables bound in outer stack frames don't affect a function's
use of variable names.)

> default arguments _are_ lexically scoped.

I'm not sure what you mean here either.  Defaults are evaluated in the
containing scope.  I'm not sure how that makes them any more lexically
