[erlang-questions] process dictionary, anyone?

Trouble is that it breaks the functional part of the language. Now that 
is only really done in process dictionary, processes/message, ports and 
ets. Though both ets and ports can be considered as processes/messages 
and can be implemented as such though a bit less efficiently.

So globals variables in the process dictionary is not really a Good 
Thing. Using them as settable constants would be perhaps ok. How about 
having them as variables and only be set-once?
