   The reason I was saying the specialized kernels might not be totally useful 
was,  my mind, that  the overhead of a type dispatch could be almost entirely 
amortized -- like if we are comparing 1000 elements in an array, an extra check 
on the array's type might not be a huge deal
   
   I don't see anything wrong with leaving all the specialized kernels 
available too (maybe it would help inlining 🤔 )
