Bug report

Bug summary
https://matplotlib.org/users/dflt_style_changes.html
On this page, mpl was not specified. I could not find it in other document with reasonable efforts.

Code for reproduction

import matplotlib as mpl
mpl.style.use('classic')

Actual outcome

Traceback (most recent call last):
  File "plotindex_2.py", line 3, in <module>
    matplotlib.style.use('classic')
AttributeError: 'module' object has no attribute 'style'

Expected outcome

It works after I changed to

import matplotlib.pyplot as plt
plt.style.use('classic')

plt is used all through the documents. Using mpl here while it really needs plt is confusing.

It would be nice to explicitly show what mpl is on that page
