Okay, that I understand - process dictionary is discouraged in Erlang, Joe
states so in his book.  He did, however, says this in the book:

One form of usage that I do approve of is to use the processes dictionary to
store "write-once" variables.

Anyhow - I'm simply trying to see if there are other ways besides process
dictionary to simulate "current" variables.  Seems like there is not.

Thanks,
