I'd be happy to file some PRs along this line, if there is interest.  C 
or C++, if there's more interest in that than in Fortran.  But, gfortran 
fails to vectorize more than 50% of the stuff I run into every day, 
including most everything which involves distinct sections of the same 
array or COMMON block.
