From a pragmatic point of view, I'd say:

Adjust the Perl::Critic rule!

I mean it's an interesting question, but probably it's not possible to duplicate all these exact implementation details.

This particular 2 args syntax OTOH is documented and legit.

and by all communist gods, why would you like to have a duplicate of STDOUT which fails globally without warning?

Probably this feature is simply broken.

    Seconding this: Perl::Critic is simply wrong here. The primary risk of two-argument open is the possibility of a "strange" filename improperly triggering the magic (How about a "file" named 'rm -rf / |'?), but in this case the filename is a literal constant and that is not possible.

    This is a bug in Perl::Critic — your particular use of the two-argument syntax is fine.
