Thanks everyone! Using Martin's example, how would I then use upcase for an
array of hashes?

I'd imagine it would be

this_array.collect do |hash|
  @map = {}
  hash.each_pair do |k,v|
   @map[k.upcase] = v
  end
end

but while the @map gives me the scope to see it outside of the block, it
looks like only the first hash within the array is passed through.
