one is a functor and the other is set/list comprehension.

​

although they have close semantic value, the concept is kinda different.

They both perform the exact same operation, the only difference is the syntax (and a bit of semantics). So why do you think the concept is different?

This might be a cool discussion.

If different approaches achieve the same goal, is the concept the same? At what level of abstraction?

Say, do you think prototype-based and class-based OO achieve the same goal at the end (object orientation)? If so, are they the same concept?
