Oops, modified this in wrong place, let me fix that. |
Previous implementation wasn't correct, as an inner iterator could have had side effects.

Playground snippet to show the bug, that it silences sideeffects in map. I think we want to fix this because we don't want our use of specialization to be user-visible or affect sideeffectfulness of iterations. |
