Raul, Thanks ". 4 is nice!
However:
0 (- [: +) 0
|domain error
| 0 (-[:+)0
I meant ;: applied to a tacit definition in quotes.
It seems that [: is distinguishing between monadic and dyadic verbs.
Try a verb that has i and i or (index and index of) or any other definition
with two versions of a verb

This does not run + monadically:
0 (- [: +) 0
That said, finding a use for this would be a stretch. (Not impossible, but not
simple.)
Also, while I am here, ^:4 will run a verb 4 times...
