structural subtyping
Combining Structural and Nominal Subtyping by Donna Malayeri:
Don't need to name [under different interfaces] all possible combinations of interesting methods.
Don't need to specify that a class implements a particular interface ahead of time.
Easy to later define new subsets of methods that are interesting.

methods are orthogonal to types
interfaces are just sets of methods, work for any type [^3]
