It does not matter if you like it or not ;-).
I do agree that "checkout -" is 100% more pleasing to the eye than
"checkout @{-1}" from visual "prettyness" point of view.
But there is a very commonly accepted long tradition for "-" to mean
"read from the standard input", so we cannot reuse it to mean "the
branch I was previously on" for every command without first making
sure the command will never want to use "-" for the other common
purpose.
That limits the context we could use "-" and we cannot consistently
use it everywhere. I find _that_ ugly from the "design cleanliness"
point of view.
