binding code snippet example not working

[sztanyi]

Following code in section 3.7. Assignment vs. Binding seems not working
my $a; my $b; $b := $a; $a = 7; say $b; $b = 8; say $a;

i got the following error message:
`

my $a
(Any)
my $b
(Any)
$b := $a;
===SORRY!=== Error while compiling:
Cannot use bind operator with this left-hand side
------> $b := $a;`

Thanks. This looks to be a REPL bug. I filed it in Rakudo as rakudo/rakudo#1565

The code from the example should work fine if you save it into a file and run perl6 the-file.p6
