Hi Elias,

nice trick!

By the way, I found a workaround to the string ordering. The workaround requires memory on the order of ↑(⍴V)×⌈/⍴¨V for a vector V. This should be enough justification for the proposed extension.

Here's what I do: instead of doing the following:

      z[⍋z←'foo' 'bar' 'test' 'aaaaaa']

┌→──────────────────────────┐

│┌→──┐ ┌→──┐ ┌→───┐ ┌→─────┐│

││bar│ │foo│ │test│ │aaaaaa││

│└───┘ └───┘ └────┘ └──────┘│

└∊──────────────────────────┘

I do this:

      z[⍋⊃z←'foo' 'bar' 'test' 'aaaaaa']

┌→──────────────────────────┐

│┌→─────┐ ┌→──┐ ┌→──┐ ┌→───┐│

││aaaaaa│ │bar│ │foo│ │test││

│└──────┘ └───┘ └───┘ └────┘│

└∊──────────────────────────┘
