S03-binding/scalars.t has a test that currently fails with "Cannot use
bind operator with this left-hand side"

  my $a = "a";
  my $b = "b";

  ($a, $b) := ($b, $a);
  is($a, 'b', '$a has been changed to "b"');
  is($b, 'a', '$b has been changed to "a"');

From @smls

Assignment works​:

  ($a, $b) = ($b, $a);

So does binding to a signature​:

  :($a, $b) := ($b, $a);

Maybe the test precedes the GLR?
Should probably check with jnthn if it still makes sense.
