Why no warning for this code?

h = {
‘foo’ => ‘abc’,
‘foo’ => ‘xyz’,
‘foo’ => 42
}
p h

I can’t think of a case where I would seriously want to do this. This
code runs cleanly on Ruby 1.6.7 and 1.7.2.

I suppose ruby can distinguish the difference between the above and:

h = { ‘foo’ => ‘abc’}
h = { ‘foo’ => ‘xyz’}
h = { ‘foo’ => 42}

or

h = {}
h[‘foo’] = ‘abc’
h[‘foo’] = ‘xyz’
h[‘foo’] = 42

The latter two should not return a warning, but I can imagine
where it would be nice for the first to.
