Programmer with perl background would think split like: <list of string> = split <regex> <original string> Since regex is involved, it is specific to (Byte)String, not a generic list. Also it appears one would need help from Text.Regex(.PCRE) to do that.
intercalate a (split a xs) = a
Right; I misspoke. What I meant was that you would want a split such
This identity rule does not hold for perl's join/split if regex is used.
