How is this any worse than syntax-highlighting a full �� construct?
Incidently, it might make matters easier if you forbid whitespace between
the �� operator modifier and its operator. Indeed, you might want to look
into including a trait for operator declarations which allows you to
modify the importance of whitespace - something like:
sub circumfix:�� (&o is infix) is whitespace(forbidden) {...}
sub prefix:� (&o is postfix|infix) is whitespace(forbidden) {...}
sub postfix:� (&o is prefix|infix) is whitespace(forbidden) {...}
