How to filter for exported resource?

[bastelfreak]

Hi!
thanks for the little face. It helped me a lot to debug some resources. I export a few defined resources and puppet node exports lists them fine:

Name         Exports
foo.local      Mymodule::Myclass['foo']

How can I filter for that? I tried:
puppet node exports --resources Mymodule::Myclass
puppet node exports --resources mymodule::myclass
puppet node exports --resources Mymodule::Myclass['foo']
