This color would save the need to glance down at the 'CurObj:' line at the bottom, yes. Given it does not seem to be a big effort to glance down, I am not sure that the savings justify an interpreter change. YMMV (or VMPV?), of course.

Quick and dirty, partly due to passing a noun as ⍺⍺:

rot←{⍺←3 ⋄ ⍺{t←⍵ ⋄ (⍺⍺↑⍺⌽t)←⌽⍺⍺↑⍺⌽t ⋄ t}∘⍵¨¯1+⍳(1-⍺)+≢⍵}

Having to use a temporary for the selective assignment does itch a bit, but it works.

Have you tried ⎕SRC⎕THIS ? I tried this very early on, found it lacking, abandoned that path. As with many other things, it may have been fixed without fanfare later on, with a recently discovered case in point: double clicking on the beginning of a line in a function edit, selects the whole line. A ...

> 'here' is opaque for new users. In the same vein, APL is opaque for new users. The solution, or so I have heard, is education. Discussion to the propriety of the name distracts. Discussion as to the format of the result (newline delimited v nested) distracts. The 'powers that be co-opted my ...

The thing about all these 'array notation' proposals is that having ⎕here would make them all user exercises, similar to what

t←⎕json ⎕here ''

would do. Phil Last could do one thing, Dyalog could do another, and all could co-exist.

Sometimes it is easier to solve the bigger problem.

Being fed-up with the baroque way multi-line nouns have to be created, impatient with the promised enhancements, and frustrated with the ease this can be done in a tradfn, where scripts seemingly make this difficult, I would like to propose a system function be added to Dyalog APL: r←⎕here delim so t ...
