Rails core - May 2010 - Extending the routing system - is it possible to output procs inside module_eval?

Hey,

I was thinking about extending Rails routing system to allow to pass
procs as default values for segments e.g.

:path_prefix => "/:locale", :defaults => { :locale =>
Proc.new
{ I18n.locale } }

but after checking the code I''m not really sure if it''s
possible.

The problem is that Rails uses module_eval with string to dynamically
generate named route helper methods like this:
http://gist.github.com/1526bf48b78eee94e6f0
Putting e.g. a proc into options hash causes invalid syntax, because
the hash is simply printed there using options.inspect.

Is there any other way to define these methods *and* allow procs in
options hash?

Cheers,
Szymon
