Please stop saying 'Python' should support this like 'Ruby' because
'Ruby' doesn't -- Rails, the application, does. Rails can do it most
of the time because it knows the particulars about Rails objects. If
you are messing with the internals of Rails I'm sure an call to
'Dispatcher.restart_application'[1] has a good chance of dying.
Complain to the developers of python _applications_ if their app
doesn't have this feature. As I said last time you b*tched about it,
there can't be a standard magic reload that works on everything.
Application developers can implement something that works for their
specific application because they know the internals.
If you are going to complain please at least post some context
about what you think should happen and some links to how other folks
have implemented it. Asserting python should do 'Reload and Go'
isn't very helpful.
