[Jprogramming] Formatting then Boxing a vector

[Alex Rufon]

Oh. 

I actually didn't understand why it was throwing a length error. I just
assumed (erroneously) that since the statement worked on one item ...
adding an each should work. Thanks for the heads-up. I'll keep this in
mind in the future.

The problem with your original 'each' was that you
needed to box x:

(<'r<0>2.0') (8!:2) each A
