Ivan,
Why the container package does not provide a type-class to unify APIs? Are there any technical/historical reasons?
Various people have tried, but they're typically unweildy, and in some cases difficult to express without using extensions. There's also tension between "this should be a class method" vs "this should be a function that uses the class" (large classes are annoying, but having a function as a class method allows for more potential implementation-specific optimisations).
Thank you for your explanation! --Kazu
