Depends. A unary ok operator would let you pinpoint very easily,
*without* using parens:
ok $fh.print($foo); # no warnings about print (closed fh?)
# but warning about undef $foo remains
$fh.print(ok $foo); # warn about printing thingies, but not about
# undef $foo
say $foo, $bar, ok $baz, $quux; # complain about everything, except
# what has to do with $baz
my $foo;
ok my $foo = "foo $bar baz"; # warn about $bar, but not the masking
my $foo = ok "foo $bar baz"; # other way around
