# Now drop all the abstract ones.

In Python 3, it's not allowed to delete a key from a dictionary while iterating over it.
Example while trying to npm install --save gl:

                              Deleting a key from a dictionary while iterating over it raises an exception in Python 3 #1998

                              # Now drop all the abstract ones.

                              In Python 3, it's not allowed to delete a key from a dictionary while iterating over it.
