In Perl 6:
class ABC {
my $x = 0;
method foo() {
$x = $x + 1;
}
method bar() {
say $x;
}
}
$x is lexically scoped, which means that methods foo and bar
need to be marked with the class block as their :outer scopes.
Similar considerations may apply for inner classes, where we
end up with methods (of an inner class) inside of other blocks.
