[racket] How can I save all the definitions in racket to a file?

No, not really :). The stress is in doing everything that is possible in
the scheme side. When Racket doesn't provide metadata i need (e.g.
procedure arg names), i obtain it by means of racket code, rather than
by 'source scrapping' in elisp. Emacs is just handling the presentation
layer, i.e., the logic that does not depend on the scheme
implementation. So all the interesting bits are computed by (modules
implemented in) Racket (and that's why Geiser needs a pretty smart
scheme implementation underneah to be really useful). As further
examples, an Emacs interface to the macro stepper is already in my TODO
list, and if some day Racket offers a way to introspect on contracts or
types (meaning the ability to manipulate them as values), i'll rush to
offer them in Geiser documentation windows.

All that said, there's still a lot of elisp code in Geiser :)
