as dave already said This could probably be optimised when pp_av2arylen is called in rvalue context.

but my example shows that your suggestion Could not the application of magic to an array, and all the penalties that go with it, be deferred until it is used in an lvalue context? would effect manipulate code at long distance.

And yes of course I consider my example to pass $#a as an argument an extremely common case.

Cheers Rolf
