Re: [Bug-apl] Extension proposal: ⍵⍵ to access outer lambda

[Jay Foad]

Note that this would conflict with the use of ⍺⍺ and ⍵⍵ in NARS2000
and Dyalog, where they refer to the operands of a defined operator.

With three levels of nested lambdas would you also want to be able to
use ⍵⍵⍵ in the innermost one, to refer to the value of ⍵ in the
outermost one, and so on?
