Changes to an `ns` form are not reloaded

[rmschindler]

When using (require 'app.core :reload) in the REPL, and there have been changes to the :requires in the ns form, I find that those changes are not honoured, and I have to stop and restart the REPL in order for those changes to take effect.

Is this by design, or is this an oversight? or am I missing something?
