+ Returns the column's name, alias, or expression as a string, in the
same
+ form shown by the column's :func:`repr`.
+
+ This is handy for reusing or inspecting a column's name, for example to
+ re-alias an expression with the source column's name, or to branch on
the
+ name inside a helper function. The leading underscore avoids a
collision
+ with the existing :func:`name` method (an alias for :func:`alias`).
