.perl and other methods on Junctions?

Consider the code: my $x = 3 | 'foo'; my $y = $x.perl; Does $y end up as a junction of strings or as a single string? Asking more directly, does .perl autothread over a Junction? If .perl does not autothread, then is there some way of knowing which methods autothread and which do not?
