If hex made "horizontal lists", it would not be a list -- it would be a single
character string, without any spaces between the two string hexadecimal
representations.
Alternatively, hex could produce a box, using rank 1 to force the "horizontal"
shape.
hex =: [: < "1 hc {~ 16 16 #: ]
hex 22
┌──┐
│16│
└──┘
hex 22 23
┌──┬──┐
│16│17│
└──┴──┘
hex 22 23 24
┌──┬──┬──┐
│16│17│18│
└──┴──┴──┘
Now, if you want to catenate them, open the boxes, append a space to each, and
ravel the results, or use another "join" function as suggested previously.
