Subject: Problem: use case stmt on object's class in simple test

Hi,

The following is a toy abstract from an app I'm writing.

hash = {:Name=>"Tom"}
hash.each_key { |key|
  puts "key %s (class = %s) => %s (class = %s)" %
    [key.inspect, key.class, hash[key], hash[key].class]
  case hash[key].class
    when String; p has[key]
    else; puts "hash[key].class not found"
  end
}


The output is:
key :Name (class = Symbol) => Tom (class = String)
hash[key].class not found

 Why isn't the "when String" statement executed?

Thanks in Advance,
Richard

P.S.  I wonder if the time will come when I won't regularly stumble
over apparent anomalies when writing Ruby code.
