There is misleading behavior though with the current implementation. For 
example:

Example1: "aaaab".split( /a/ ) => [ "", "", "", "", "b" ]
Example2: "a".split( /a/ ) => []
Example3: "aaaa".split( /a/ ) => []

You would think all three cases would respond the same, but the last 
examples respond very differently then the first. Should the behavior 
not be consistent?
