Rake::Task class has a clear() method for removing actions and prerequisites from task. Would it be possible to provide method like this for Rake::NameSpace to remove all tasks?

Also, there is no (at least I couldn't find any) method for searching for namespace like [](task_name) in Rake::Task. There is [](name) method in there, but it searches for task in namespace.

These two features could enable one to write:

Rake::NameSpace.get('namespace_name').clear

Where get is a bad excuse for a method name that returns namespace by name.
