Speaking of variables, namespacing (as implemented) does absolutely nothing 
to help the following type of situation:

-- Customer file:
global object rec
global constant NAME = 1, ADDR = 2, CITY = 3, STATE = 4

rec = {"Coyote, W.","55 Fifth St.","Tucson","AZ"}

-- Supplier file:
global sequence rec

global constant NAME  = 1, STATE = 2

rec = {"Acme Anvils, Inc.","PA"}

-- Main program:
include customer.e as customer
include supplier.e as supplier

printf(1,"Name:%s, State:%s\n",
       {customer:rec[customer:NAME],
        customer:rec[customer:STATE]})

Anyone else note a great duplication of effort here?
How do you get the same result without qualifying every 
instance of NAME and STATE?

Anyone remember how easily that was done with ancient Pascal?
