Imagine a function that checks the environment as to what encoding or human language and so on to produce text in. If you cache it so it produces results that are stored in something like a dictionary with a key, and later the user changes the environment as it continues running, the cache may now contain invalid results. You might need to keep track of the environment and empty the cache if things change, or start a new cache and switch to it.  An example would be the way I use Google Translate. I sometimes am studying or using a language and want to look up a word or phrase or entire sentence. If Google Translate keeps track, it may notice repeated requests like "Valentines Day" and cache it for re-use. But I often click to switch languages and see if the other one uses a similar or different way to describe what it means or something similar but spelled another way. German does the latter as in Valentinstag which is a fairly literal translation as does Dutch (Valentijnsdag ) and  Hungarian (Valentin nap) .

The Esperanto didn't look right to me; it's "Valentena tago" or 
"Sankt-Valentena tago".
