All right. I think I'm starting to understand the reasoning that went into
the spec as written. Thank you for giving me the necessary pointers.
Now, that leads me inevitably to the obvious followup question: Is there a
way to run "my" version of this operator?

OK, I understand your explanation, and I have to say that the spec seems to
be a bit over-specif

It if does what you need then sure, but it's a very different thing
than scan:
,\'abcd'
a ab abc abcd
2,/'abcd'
ab bc cd
-
I see. So the way I see it, I should actually use 2 *OP*/X instead? I seems
to actually do what I expected.

The following code returns the expected results:
* {⍺+⍵}\⍳10*
1 3 6 10 15 21 28 36 45 55
However, if I also print all the calls, I get a lot more evaluations of the
function than expected:
*{(⍺+⍵)⊣⎕←('[',(⍕⍺),',',(⍕⍵),']')}\⍳10*
[1,2]
[2,3]
[1,5]
[3,4]
[2,7]
[1,9]
[4,5]
[3,9]
[2,12]
