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|
+-----+

Quote:

         {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 :-)
