Data.CaseInsensitive.Eq
Description
This, like most other case-insensitive matching algorithms, is an over-simplification. For some complex Q&A about properties like case, see http://unicode.org/faq/casemap_charprop.html. A round-trip case-conversion does not necessarily result in the original character(s) in some scripts. Also, string matching is not necessarily the same as character matching. The char-at-a-time approach taken here is not technically correct, but works for the most scripts, and definitely for ASCII and the ISO-8859-1 8-bit Latin 1 character set.
Usage is simple:
main = putStrLn $ if "HREF" ^== "href" then "match" else "no match"
