I don't understand this no it doesn't, the logic I outlined can be boiled down to

If I only need to do X

And X cannot do Y

Then I do not need to do Y

-----------------------------

If I need to do Y

And X cannot do Y

Then I need to do something other than X

-------------------------

Give your answer of no it doesn't please be so kind as to outline the logical reasoning that you are envisioning?

on edit: added line between logical statements.

Unless I've misunderstood you, you said that, for example, `continue` cannot be implemented in terms of `map`, which simply isn't true. It's trivial.

I thought the original statement was break or continue, I was actually focusing on break? As far as I know you don't break in map, you can return null but not break the loop itself.

on edit: although I almost never break in a loop, I use some other construct instead.

on second edit: maybe I should say iteration instead of loop but will let it stand.

It's not clear to me what you're trying to achieve. Sorry.
