Subject: how to unset a hash member?

how do i unset a hash member (as in php)?

h['a'] = 'aaa'
h['b'] = 'bbb'
h['c'] = 'ccc'

h >> { 'a' => 'aaa', 'b' => 'bbb', 'c' => 'ccc' }

something like this:
h['b'].delete
h >> { 'a' => 'aaa', 'c' => 'ccc' }

not like this:
h['b'] = nil
h >> { 'a' => 'aaa', 'b' => nil, 'c' => 'ccc' }

thanks. :)
