Aha, I suspected as much, but being so new to the language I thought I
would ask here to be sure.
Thank you so much for your work on GNU APL. I still don't know exactly how
or where I'll use APL, but I am enjoying how it directs one to think about
problem-solving.

Hi Russ,
welcome to APL. And welcome to bug-apl@gnu.org. The latter is a
moderated list, so please subscribe to
it because otherwise each of your emails will require (manual)
approval by myself.
Back to your question, ⍸ is definitely not a stan
No problem!
Your (⊂ 1 2) (/¨)¨(,¨)'ab' can of course be golfed:
(⊂1 2)/¨¨'ab'
a aab bb
Or, in Dyalog:
1 2∘(/¨)¨'ab'
a aab bb

Hi,
In my mind I mostly think in "elements" - not rank or shape.
That is "L-element OP R-element" . Where elements have an empty rank
(scalar, ⊂..). And APL takes care of ranks, shapes and depth.
⍝ as you mentioned (and I had to remember): 'a' 'b' ≡ 'ab'
⍝ that is a vector of single chars i
