it's not a priori choice
i know when to use interface, extension method,and the member method.
i mean if i have method it's name is map like select, i want type to have it(i can edit type),(i don't need to make the type interchangeably or use it in polymorphism) i make map as a member method in it, or as extenion method, or interface
only i need any type that has map to be mapable, mean(has method map)

only i need any type that has map to be mapable, mean(has method map)So you're saying you don't know if the type has
Map or not at compile time?
