Methods
Public Instance methods
Check for deprecated uses of top level (i.e. in Object) uses of Rake class names. If someone tries to reference the constant name, display a warning and return the proper object. Using the —classic-namespace command line option will define these constants in Object and avoid this handler.

Check for an existing method in the current class before extending. IF the method already exists, then a warning is printed and the extension is not added. Otherwise the block is yielded and any definitions in the block will take effect.
Usage:
class String
rake_extension("xyz") do
def xyz
...
end
end
end
