And when we finally find a very general solution, the specific case of
"split colon-separated fields" requires some thought and three lines of
code using higher order functions and pattern matching, instead of just
   splitSep (== ':') line
:-)

Make simple things easy, complex things possible. Concentrate on the
first part. Generalize only if it doesn't make the common simple case
harder. After all, one always can write a complex splitting function
by hand. The simple version doesn't have to cover all possible
generalizations, only those which don't disturb common cases.
