Finalise variables #44
Description
How could finalising variables like in Scala be implemented in RM BASIC? From FB:
"Scala has assignments like "var x = 1.0" (can change) and "val x = 1.0" (cannot change). What I liked was that it doesn't take any extra typing to make variables final. Personally I'd have all variables final unless specified otherwise. Or you could have some alternative assignment operator instead of := to make it final."
