Legal in perl5:

 my $foo = foo( 1 );
 my $foo = foo(1);
 my $foo = foo (1);
 my $foo = foo      (    1
           );

 my $foo = $object->method (1)
                  ->method (2)
                  ->method (3);

NOT legal in perl6

 my $foo = foo (1);
 my $foo = foo      (    1
           );

 my $foo = $object.method(1)
                  .method(2)
                  .method(3);

But with Slang::Tuxic they are!
