function to split strings and lists on predicate

[Mark Lawrence]

I came across this over the weekend 
http://paddy3118.blogspot.co.uk/2013/10/unifying-pythons-string-and-list.html. 
  I couldn't come up with a solution to the fsplit function that seemed 
in any way cleaner.  What can our nest of avid Pythonistas come up with?

My fellow Pythonistas, ask not what our language can do for you, ask 
what you can do for our language.
