Subject: new user confused by multidimensional Ruby hashes

Hi all,

[ianmacd@caliban ~]$ irb
irb(main):001:0> foo = Hash.new( {} )
{}
irb(main):002:0> foo["bar"]["baz"] = "foo"
"foo"
irb(main):003:0> foo
{}
irb(main):004:0> foo["bar"]
{"baz"=>"foo"}

Can someone please explain to me why, in line 3, 'foo' is empty instead
of containing the single element 'bar'? foo["bar"] contains the element
'baz', so why does 'foo' not contain the element 'bar'?

I'm used to Perl, as the foregoing probably indicates ;-)

Ian
