By IRC, dkubb say me we can avoid some freeze on some NameSpace by using the IceNine::Freezer::NoFreeze.
By example if I want not freeze by IceNine all object in RSpec you can do :
class RSpec < NoFreeze
Can be really usefull in your test.
Maybe a configuration in IceNince can be more easy with a design like :
IceNince.no_freeze_namespace([Rspec, Spec, Mocha])
That's a good idea. I may add something like IceNine.no_freeze(*mods). I would then exclude a few common namespaces like Spec, RSpec, Mocha and Test.
Add method to simplest the NoFreeze system by adding a class method
If you want not freeze some namespace you can do
