sorry if it's been discussed as i don't know what the search keyword
for this scenario. it actually came up from _mistype_ (notice the
comma).

m:~ arie$ irb
>> h = {}
=> {}
>> h[:a] = 1,
?> h[:b] = 2
=> [1, 2]
>> h
=> {:a=>[1, 2], :b=>2}

This is expected behavior. You've assigned a two-element list to h[:a]

- the number 1
- an assignment expression yielding the number 2

Since assignment expressions return their rval, everything's happy and legal.

This one-line version behaves identically to what you've typed:

h[:a] = [1, h[:b] = 2]

Feature, I think. Otherwise, you wouldn't be able to do things like...

a, b = b, a

The comma, it seems, assumes precedence from the right side.
