Example

Example 1: Create a store, set a value and retrieve it both with store-ref and with store-timedref

> (define store (make-store "main"))
> (store-set! store "HR" 78)        
> (set! ##now (+ ##now 31.))  ;; This is a terrible hack to advance the clock on Console
> (store-ref store "HR")
78
> (store-timedref store "HR")
#f
