|Ah, your preference is for Ruby 1.9 code to convert external key/value

Don't take me too serious (although I know it's difficult, since I am
the responsible).  I have never felt I need HashWithIndifferentAccess
in my programming life, so my opinion is biased.  You've explained
somewhat in [ruby-core:26507], but I still need more comprehension.
In general, blurring type differences (string and symbols in this
case), is a code smell.
