Subject: Re: populating a hash from an array using inject

Sorry, I pasted the ri output on top of the first part of my post, which 
said something to the effect of:

> My question: why is bar empty?

...because h[non_existent_key] sends an array that is unassociated with 
any hash to the block.  In other words, creating a hash with a default 
value does not cause a key/value pair to be created in the hash when a 
non-existent key is accessed.
