push method on hash?

Is it possible to push items into a hash in a similar way you do with an array?

If so, I do i push an item into the key, and push into a value?

thanks

hash = {}
hash["key"] = "value"
=> {"key" => "value"}

hash[:another_key] = :another_value
=> {"key" => "value", :another_key => :another_value}

hash.store(:yet_anotherkey, :yet_anothervalue)
=> {"key" => "value", :another_key => :another_value, :yet_anotherkey => :yet_anothervalue}

Couple of different methods there (the 'store' method is preferable sometimes for readability).

Thanks Andrew.

What if i want to store stuff from within a function into a hash outside of the function?

I know that with push method and arrays, this will work, but with store and hashes, it doesnt work. (I know there is a name for this sort of thing, but i cant think of it right now... maybe global?)
