I'm not sure it even gets to the point of evaluation :-). At least in Perl 5.8.8 attempts to pass a first parameter without an @ sigal produces compilation errors. You don't even need strictures to produce them: 
our @x;
sub foo {
  print "wantarray? ", wantarray?1:0, "\n";
  push @x, (1,2,3);
  return @x;
}
pop foo();

generates

Type of arg 1 to pop must be array (not subroutine entry) at Monks/Sni
+ppet.pm line 7, near ");"
Execution of Monks/Snippet.pm aborted due to compilation errors.

The same compilation error results if one tries to use a subroutine to generate the first parameter of push as well. Replacing pop foo() with push foo(), 4 results in

Type of arg 1 to push must be array (not subroutine entry) at Monks/Sn
+ippet.pm line 7, near "4;"
Execution of Monks/Snippet.pm aborted due to compilation errors.
