Subject: strange SDBM behaviour

hi gurus and nubys,

I just noticed this:

>> db=SDBM.new 'foo', 0666
=> #<SDBM:0x28b3130>
>> db[:foo]=10
=> 10
>> db.keys
=> ["foo"]
>> db[:foo]
TypeError: cannot convert Symbol into String
        from (irb):8:in `[]'
        from (irb):8

It seem that []= uses to_s while [] uses to_str:
>> class C
>>  def to_s
>>   'miao'
>>  end
>>  def to_str
>>   raise 'fuku fukissimo fuku'
>>  end
>> end
=> nil
>> db[C.new]=30
=> 30
>> db.keys
=> ["foo", "miao"]
>> db[C.new]
RuntimeError: fuku fukissimo fuku
        from (irb):16:in `to_str'
        from (irb):21:in `[]'
        from (irb):21

is this an expected behaviour? I believe wheter SDBM  uses the one or
the other it should be consistent in hi choice :)

Anyway:
ruby 1.8.1 (2003-12-25) [i386-mswin32]

Can't say what version sdbm is, given that VERSION refers to 1.8.1 and
SDBM::constants == []
