Read the article, that was discussed and dismissed. It doesn't make accio 'act as import' because import is a keyword not a function call.
In [1]: accio = __import__
In [2]: accio("os")
Out[2]: <module 'os' from '/usr/lib/python2.7/os.pyc'> >>> accio = __builtins__.__import__
>>> accio sys
File "<stdin>", line 1
accio sys
