Hm. So how are valid parameter names defined? Identifiers in perl6 seem to be composed of letters, digits and underscores (and hyphens and apostrophes between letters). Are parameter names defined differently? You certainly seem to be able to declare a variable $1.
I believe that Perl 6 identifiers can be any string at all, but that then they have to appear quoted in the general case; the above restriction just refers to the common case of unquoted identifiers. This said, I'm not sure yet what the syntax is for quoting identifiers. -- Darren Duncan
