I think the main problem isn't the length of variable's name but the
fact that regular variable is neither lexically scoped nor localized.

Using ⍵⍵ might be confusing for Dyalog users where ⍺⍺ and ⍵⍵ are used
as functional arguments of dfn operators.  But since GNU APL uses ⍶
and ⍹ for those and it doesn't localize variables in dfns, using
repeated ⍺/⍵ for nested arguments doesn't sound that bad.
