Subject: Re: iterating methods on multiple parameters

I just saw a similar issue (#163350 of this forum).

seems like this might work to change values of a hash:

hash = {'x'=>2, 'y'=5}
hash_new = hash.inject({}) do |h, (k,v)|
  h[v * 2] = k
  h
end

although this returns {10=>"y", 4=>"x"}

something seems amiss...

what do you think?
