Elias,
This was an extension to Mix in Dyalog 14.0
(http://docs.dyalog.com/14.0/Dyalog%20APL%20Release%20Notes.pdf p22)
inspired by the way the Rank operator assembles results with differing
ranks. I'm not aware of any other APL2-like APLs implementing this
extension.

Fair enough. That said, I think dzaima/APL implements it. As does KAP now.
It's also a pretty obvious implementation, and the behaviour orthogonal,
instead of having a special case for scalars.
Regards,
Elias

Apart from compatibility with Rank (which didn't exist in Dyalog before
14.0), why do you think adding leading ones to the shape is "obvious"? Why
not trailing ones, for example?

Hi,
if we look at the rank operator in ISO APL (which is not present in IBM
APL 2) then they
define an operation "conform" which reads:
*conform: *The shape of a result is the frame of the argument (relative
to the cells to
which the function applies) catenated with the shape of the individua
