    4343  * !SumSquares [FINE] 
    4444  * Dot product [FINE] 
    45   * Evens '''[OK, but more than 3 times slower than C]''' '''[ROMAN (might affect Quickhull due to packByTags]''' 
     45  * Evens '[OK (but more than 3 times slower than C)]' 
     46    * rl reckons this is due to GHC compiling modulo of powers of two inefficiently; c.f., #3065 (in `packByTags`) 
    4647  * SMVM '''[SLOW (lack of fusion)]''' '''[BEN & ROMAN]''' 
    4748 * Dynamically-nested DPH programs without user-defined datatypes should run correctly, but not necessarily fast 
    4849  * Quicksort '''[BROKEN (SpecConstr) & SLOW]''' '''[SIMON & BEN]''' 
    4950  * Quickhull '''[OK, but has  a SpecConstr problem that we want to fix]''' '''[ROMAN]''' 
     51    * Probably affected by the same optimisation issue with the compilation of modulo operations as Evens 
    5052 * Dynamically-nested DPH programs with user-defined datatypes should run correctly, but not necessarily fast 
    5153  * Words '''[BROKEN (SpecConstr)]''' '''[SIMON]'''
