Subject: inject's pathological case...

    I'm not sure how I feel about inject's pathological case.  What do you 
all think should happen in the following code?


[2].inject {|a, i| puts i}


    I might have thought that the block would never be called and the method 
would return 2.
    If the block must be called, I might expect "i" to be nil.
    What actually happens is that the block is called and "i" is the same 
thing as "a".  I did not expect this and I'm trying to figure out how this 
is either consistent or useful.  Can someone clue me in to this behaviour?
    Thank you...
