NAME

Slang::Roman - lets you use Roman numerals in your code

SYNOPSIS

use Slang::Roman;

say 0rI + 0rIX; # 10
my $i = 0rMMXVI; # $i = 2016

DESCRIPTION

This bit of admittedly twisted code let you use Roman numerals in your Perl 6 code. It patches the running grammar so you can use a Roman numeral anywhere you would use a regular integer.

Future enhancements will include expansions to printf/sprintf with a custom formatting type, and the equivalents of hex() to handle string conversion.

While it handles both additive and subtractive Roman numerals, it doesn't check that they're properly formatted. For instance 'IC' should be a compile-time error but instead it'll generate 101 as if nothing of consequence happened.
