I think it doesn't scale. ;-}  I muchly prefer my own #$ readmacro
[or one of the many similar variants discussed here last December]:

    > (mapcar #$(+ (* 100 $2) $1) '(1 2 3 4) '(5 6 7 8) '(9 10 11 12))

    (501 602 703 804)

An unintended [but nice] consequence of the implementation
[it just uses READ to pick up the LAMBDA body] was that it
can also be used as an abbreviation for CONSTANTLY:

    > (mapcar #$57 (iota 10))

    (57 57 57 57 57 57 57 57 57 57)
