nope it's inconsistent, and any breach of orthogonality is a pain in the *ss and should at least be better documented.

> And since you appear to want undef to be "a legal value", there is no value that shift could return to indicate that the array is now empty.

So according to you, the demonstrated code using splice is a programmers error!

Of course shift should return an empty array which is false.

And of course ($x)=() would result in $x=undef without being true. This would be consistent with Perl's usual behavior.

  DB<196> $x=42
 => 42

  DB<197> ( ($x) = () ) ? "$x" : "false"
 => "false"

  DB<198> $x
 => undef
