In terms of performance, it still bugs me that APL doesn't have suffix scan (or LTR-evaluated scan).

VALUE ERROR
Okay, the result is like
  -/t → 3.5E¯5 |      0%
* -\t → 3.9E¯6 |    -89%
* ⊣\t → 1.7E¯2 | +48977% ⎕⎕⎕⎕⎕⎕⎕⎕⎕⎕⎕⎕⎕⎕⎕⎕⎕⎕⎕⎕⎕⎕⎕⎕⎕⎕⎕⎕⎕⎕⎕⎕⎕⎕⎕⎕⎕⎕⎕⎕
So I guess -\ is special-cased, ⊣\ is not (and is taking quadratic time as expected).
