Yes, I've done that too.
The point is that there are ways to get a constant verb (or one could be
defined), but no easy way to get the effect of +`-"n .

longer and I find that it better explains what I am trying to do.

Conciseness?
I guess it's debatable whether constants with non-infinite rank are
more or less common than gerunds which need to conform to the shape of
their (eventual) verb argument.
Perhaps it would be worthwhile collecting useful examples of each? I
know I've used low-rank constants within the last few years, but at
the moment I do not remember where...
Thanks,

A constant verb (with rank _) can be produced easily via &[. For example,
(1 2 3 &[) _
1 2 3
and it could be followed by a suitable rank (") form if necessary. Am I
missing something?

All the partitioning modifiers (\ /. \. ;. etc) allow u to be a gerund
that is applied cyclically to the partitions. Thus, +`-/. applies + and -
alternately.
All the modifiers, that is, except one. The simplest one. One that
perhaps wasn't thought of as partitioning, though it clearly does. It
partitions the y argument into cells.
If m"n had been defined consistently with the other partitioning
modifiers, we would be able to write +`-"_1 to have different verbs applied
to items. This would have saved dozens of emails over the years searching
for a good way to perform this often-needed operation.
The constant-verb would have to move somewhere else: m&n, m@n, and many
other places are free.
For the next language.
