[Haskell-cafe] Roman Numeral Problem

Hi. I am working on some practice programming problems, and one is the Roman numeral problem: write a program that converts Roman numerals into their (arabic) numeral equivalent. I imagine I could hack something together, but I was trying to think about the problem a bit more deeply. I don't know much about parsing, but I was wondering if this problem matched up with some kind of parsing or grammar or other generic approach to thinking about the problem. (I once read something about Context Free Grammars, which was rather interesting.) I can do more of my own research if I can get some initial guidance. -- frigidcode.com
