Bug summary

The handles parameter for mpl.legend.Legend is typed as Iterable[Artist], but I believe that legend handles can also be artist tuples to produce a combo legend annotation?

Code for reproduction

# This works anyway

import matplotlib as mpl
import matplotlib.pyplot as plt

f, ax = plt.subplots()
h1 = mpl.lines.Line2D([], [])
h2 = mpl.patches.Patch(alpha=.2)
ax.legend(handles=[(h1, h2)], labels=["combo artist"])

Actual outcome

MyPy error when I pass a list of artist tuples to mpl.legend.Legend.

Expected outcome

I think this is valid matplotlib?
