Yeah, I think we've all done something similar. Myself,
I called it #$ and used shell-like ${digit} as params:

> (mapcar #$(= $1 5) '(1 3 5 7 9))

(NIL NIL T NIL NIL)
> (mapcar #$(* $1 1.085) '(12.34 15 10 25.37))

(13.3889 16.275 10.85 27.52645)
> (mapcar #$(> $1 $2) '(1 2 3 4 5) '(5 4 3 2 1))

(NIL NIL NIL T T)
> (mapcar #$$2 '(1 2 3) '(4 5 6) '(7 8 9))

(4 5 6)

But I use this *only* at the REPL when poking around,
*never* in saved source files...
