It sounds to me like manual reference counting in an environment where
automatic garbage collection is available; I would prefer a little
slower optimization, which memoizes pointers to strings and compares
strings by reference, then by value. It will be almost as fast 
for most applications, and the user will have the freedom to do exactly the
same to optimize -- to predeclare the names in one place, without
keeping extra variables when it does not need to.
