Rakudo r32373:
$ ./perl6 -e 'sub f($x) {$x++}; my $y = 2; f($y); say "still here"'
still here
that should die, because subroutine arguments are read-only by default.
A test for that is in t/spec/S06-traits/misc.t.
Note that assignment already dies as it should:
$ ./perl6 -e 'sub f($x) {$x = 3}; my $y = 2; f($y); say "still here"'
Cannot assign to readonly variable
...
(there's now also a test for that in the same file).
