You do realise that you aren't passing the array into modify()? You're passing a list. And that list is being aliased.

And prior to the mostly pointless, blanket constanisation of the Perl sources, the (incorrect) attribution of a null C pointer to a scalar would not have been spuriously attributed to a "read-only value".

Two mistakes collide here:

  1. The lazy definition of an api that takes a list of pre-existing and defined variables as input in order to provide output.
  2. The retroactive application of const'ing at the C-level with callous disregard to the affects at the Perl level.

Upshot: p5p have buggered Perl5 in their attempts to 'be correct'.

In the absence of evidence, opinion is indistinguishable from prejudice.
