TODO: <a href="https://golang.org/cl/187519">https://golang.org/cl/187519</a>: allow embedding overlapping interfaces
Per the <a href="https://github.com/golang/proposal/blob/master/design/6977-overlapping-interfaces.md">overlapping interfaces proposal</a>,
Go 1.14 now permits embedding of interfaces with overlapping method sets:
methods from an embedded interface may have the same names and identical signatures
as methods already present in the (embedding) interface. This solves problems that typically
(but not exclusively) occur with diamond-shaped embedding graphs.
Explicitly declared methods in an interface must remain
<a href="https://tip.golang.org/ref/spec#Uniqueness_of_identifiers">unique</a>, as before.
