pointers are essentially on the same level as floats and symbols. 
Together they are the three main atom types of Pd and have corresponding 
reserved selectors and all assumed to have one argument.

gemstate messages (GEM), grid messages (GridFlow) and packet messages 
(PDP) are normal "meta-messages" in the sense that they don't correspond 
to one atom type of the same name. However, those three meta-messages 
carry abnormal pointer atoms: such pointers are not accepted by [get], 
[set] and even [list] ! That is because Pd's concept of pointer is too 
limited and also it doesn't allow externals to define their own 
atom-types.
