map() returns a list of arbitrary expressions, whereas grep returns
the elements it is processing, so it makes some sense that grep
returns lvalues while map does not. Incidentally, I didn't say the map
trick didn't have a high blink factor. It is at least as high as
@{[@foo]}.
Also incidentally, the blink factor is not synonymous with bad
programming, although there's definitely some overlap. Anything that
causes a reader to have to pause to decipher it has a blink factor.
Good programs reserve those for code that is doing something special.

What makes an explicit copy "ugly"? Especially when it avoids the
overhead of slinging an entire array around?
Would you offer an example of a prudent and common use of @{[@foo]}}?
My impression is that its only use is as protection against loop
aliasing, and it's generally more economical and clear to copy one
scalar than the whole array.

I did find it, thanks.

I think you may have mistaken my comments on this topic. There are two
points I was making:
1. there is no reason to use @{[@ar]} to solve the problem under
consideration
2. @{[@ar]} is odd enough that someone browsing the code will "blink"
when they hit it.
I think we agree on #2. Brian, on the other hand, suggested that it
was something to get used to (to the point that it is immediately
understood whenever encountered).

Yes, it is. However, making an anonymous copy of the array is not the
way to go to avoid modifying your array in a loop. There may be good
reasons for making an anonymous copy of an array, although I haven't
come up with any.
I can see wanting to do [@ar], and I can certainly see @$ref, but not
instantly dereffing a newly-created array ref.
If the question is how to avoid the side-effects of loop variable
modification, the answer is to make a local copy of the loop variable,
not to copy the entire array.
