It's harder to tell in haukex's version though (without the -exec option) because the shorter version as an extra:  <@> scope vK ->- so it's kind of hard to say that the scope is obviously missing :P. I'm guessing that this is the local scope, that makes local work as intended, but the scope that is *enter*ed and *leave*d (yes I very English, thank you) in the longer version is the lifetime of the scalar.
