Sure, I've been meaning to do this.  Originally tests/ was supposed to 
contain different test suites - there was going to be a pure Haskell 98 
test suite and some separate tests for libraries, but I think the last 
vestiges of these were removed recently by Ian.

My fingers have learned te<TAB>te<TAB>g<TAB> so it'll mess me up for a 
while but I'll get used to it :)
