Currently DB2 has makes a distinction between variable assignment and retrieval:
reading a variable is one command (.variable)
storing a variable is two commands. (.variable store)
Retrieval is implicit, storage explicit. What is the reason for this? For consistency one would expect .variable store and .variable read (both explicit, 2 BP) or .variable and something like >variable. (both implicit, 1 BP). As it is now it is easier for a bot to evolve variable retrieval than to evolve variable storage. I expect evolution sims to be faster (and or more interesting) if both are implicit. How is this giong to be done in DB3?
