You interpret it incorrectly. The problem is in your '#`{' comment. You have a
space between the backtick and the opening brace. Therefore it's interpreted as
a single line comment. Though even if you remove the space the compiler will
complain because it wouldn't find closing } due to unbalanced opening one at
line 13. Note that comments treated as-is literally, backslash doesn't escape
the brace. To get what you want you might use '#`{{ ... }}` form of
opening/closing braces. In this case Rakudo will not try to balance the sinlge
opening one inside the comment.
