I like this:

rather than:

    (unpack #:source #$(package-source racket-vm-bc))

to make it easier for a user to provide an alternate source.

My concern with:

    (unpack #:source #$(or (package-source this-package) %racket-origin))

is less strong, but if `(gnu packages racket)` exports `%racket-origin`, it 
seems like it would be very tempting to put it in a `source` field, but of 
course that would cause problems. My hope was that having to write
`(package-source racket-vm-bc)` might prompt a little more thought.

Thanks!

Will do, sorry! (I've been experimenting with MUAs recently and not getting 
everything right—you may have noticed I sent mail earlier from an address I 
wasn't intending to use.)
