I'll get the answer to this one right. <"r is heavily optimized. Don't
try to replace it.

Yes. The documentation describes exactly what's happening. The rank 1 is
the key making each number an item. In this case it is the equivalent to
(<"1) by itself. So, is it a good idea to use ({) in place of (<"1) when
wanting to box something rank 1? It's shorter and simpler to read. But what
about optimization? It seems to me that it would be a neat example in NuVoc.

As I read Ye Dic, ({ i. 2 4) should give the same result as
({ <"1 i. 2 3).
I never thought I'd have to say this to *you* but:
note that Catalogue { has rank 1.
Hence there should not be any interaction between the colors in
{ 'black' ,: 'green'
nor in the low / high vectors in
{ i. 2 4
To me, Catalogue { works just fine as-is. In particular, the DoJ
also covers the "open argument" case as it stands.
{ 'black' NB. the same as: { 'b' ; 'l' ; 'a' ; 'c' ; 'k'

|black|

{y forms a catalogue from the atoms of its argument, its shape
being the chain of the shapes of the opened items of y . The
common shape of the boxed results is $y .

[PS 1: the empty shape of the resulting box
$ { 'black'
happens to be a concatenation ("chain") of the five empty letter shapes
here.
PS 2: Those reading down to here may also be interested in this
short exercise:
What's the result of
{ 'ht' ; 'ao' ; ,. 'gtw'
?
(Just follow the instructions above :-)
