[Haskell-cafe] Split and substitution using regex-pcre

I could not find the perl-equivalents of these functions on Hackage, so I quickly wrote mine. Code is there: https://github.com/bartavelle/pcre-utils It should behave like perl (not really tested actually), and do strange things like :

splitCompile "a" "aaaab" Right ["","","","","b"] splitCompile "a" "aaaabaaa" Right ["","","","","b"]

This will go on Hackage as I need it for the language-puppet package, but I am interested in comments, especially concerning the namespaces: * is the name of this package OK ? * is the name of the package OK ? * should I work with the regex-pcre maintainer to try to merge it ?
