@pollmeier @ryanlecompte what about map on structures that are not Iterable, or even nothing like collections at all?

@dibblego @ryanlecompte well all you need is the CanBuildFrom factory. No need for Iterable or anything collection like ;)

@pollmeier @ryanlecompte but then I must implement methods that are not sensible for my "thing with map."

@dibblego @ryanlecompte all you need to implement is CanBuildFrom, which essentially needs a new Builder. looks quite sensible to me...

@pollmeier @ryanlecompte There are a bazillion things with a map method, as it is well defined, but are not collections. Still sensible?

@dibblego agreed, it would be nice if we always got the builder for free. However the post is simply about using CanBuildFrom...
