Hi Louis, I believe the problem is not finding useful applications for the not yet exploited valence variants of APL primitives. Every such extension of the APL syntax creates a new incompatibility and should be avoided in the first place. If I remember correctly then there was only one case so far where a primitive in GNU APL was extended beyond what IBM APL2 provides: monadic ⍳ for higher ranks (taken from Dyalog APL). That extension was actually simplifying APL because it was removing a historical limitation of monadic ⍳ and made it more general. Using ↓ for ¯1↑ is, IMHO, not entirely convincing and could confuse people more than it helps. Best Regards, /// Jürgen On 10/10/2017 08:06 PM, Louis de

Since the subject has been brought up, how about using it as the analog of first (monadic take), but instead unboxing the last element of an array in ravel order? |
