Thanks - I guessed as much, but isn't there also another Boost-style library for 
Ruby? (Boost is essentially Facets for C++ - a repository of reference 
implementations for future Standardization, complete with their implications.)

It's okay, but...

If I already have an array, I have to splat * it in:

   my_hash.slice(*array)

Why doesn't slice do the flatten trick here?

     keep_keys = [keep_keys].flatten
