Isn't that actually part of the Standard Perl6 Rule Library?
class Perl6::Rules {
our @HexDigits = 0..9, 'a'..'f';
our @OctDigits = 0..7;
our @DecimalDigits = 0..9;
rule ParseNumber(@digits) returns Int
{ :i [0x]? [$digit := <@digits> { $0 *= @digits.elems; $0 +=
@digits.indexof($digit) }]+ }
&ParseHex := &ParseNumber.assuming :digits(@HexDigits);
}
with &*hex being some sort of alias to Perl6::Rules::ParseHex?
Umm... can you call a rule as a function?
rule foo { .* }
$x = foo("I am the very model of a modern irregular expression");
Or do I not want to know the answer to that?
