There was a problem hiding this comment.
This doesn't apply function to tensor when targetp.
This change isn't actually necessary for map because we have map-to above.

Similar to the issue above, this change doesn't actually scale the elements of tensor into target but rather scales the elements of target itself.
Edit: My recommendation is to add a function scale-to modeled after map-to.

Intended to complete #175
Let me know if this works.
And I can add for more functions, but is there any exhaustive list on mind?
