The conversion routine 3!:4 only accepts scalar or vector arguments.
Would it be possible to extend it to behave in a similar way to #. and #:
The following is a model:
ic =: 3!:4
cnvt =: ( 3 : ' ($y)$_2[\ 1 ic ,y') :. ( 3 : '(}:$y)$_1 ic,y')
$ cnvt i.20 30 40
20 30 40 2
(-: ]&.cnvt ) i.20 30 40
1
As presently implemented:
1 ic i.20 30 40
|rank error: ic
| 1 ic i.20 30 40

PS: On a lesser point, why does the following produce a spelling error?
test =. (+):.(-)
but this doesn't
pp=. (+) :.(-)
