I wonder if I may have been misunderstood.  What I was trying to say
was:

I wholeheartedly applaud the following decision by ruby-core:

"It may lead to difficult bug to indeterminately fail to add a new
key. So, I propose to permit only updating value of existing key, and
to always prohibit adding a new key: [...] This does not cause
compatibility problem because this just raises exception that has
already been occurred indeterminately."

I believe this is the correct decision, and I would have been
disappointed if instead the indeterminate behavior were allowed to
remain.

Bill
