    Create a :class:`Timer` instance with the given statement, *setup* code and
    *timer* function and run its :meth:`.timeit` method with *number* executions.
 
+   .. note::

+        Because :meth:`.timeit` is executing *stmt*, placing a return statement
+        in *stmt* will prevent :meth:`.timeit` from returning execution time.
+        It will instead return the data specified by your return statement.
