Hexadecimal integers

[masak]

Like this:

my one = 0x1;

(Binary 0b and octal 0o is fine too, but not as important.)

This one should be fairly straightforward, actually... once we have the ability to inject arbitrary grammar terms. Here's a possible implementation:

macro term:hexint (digits) is parsed(/ "0x" (<[\d a..f A..F]>+)/) {
    my value = parseHexdigits(digits);
    return new Q::Literal::Int { value: value };
}
