I don't know a single professional programmer that can't get by without
global variables.  Furthermore, if a programmer feels he/she _cannot_ get
their work done without globals they (IMHO) either need to:  1) graduate from
college and begin working in the industry, or 2) find another career.

Erlang may need work in some areas, but the lack of globals and the inclusion
of things like single-assignment variables are _features_, not bugs.  I would
hate to see these features added so that Erlang can turn into every other 
language out there.  The person that refuses to pick it up because it lacks
global variables and the like may never "get it"...
