In order to avoid memory consumption issues there could be a centralized cache as for regular expressions. It makes it easier to handle eviction based on various parameters, and it saves a few bytes for string objects which are never used as a formatting template.
Good idea! I suggest you hook into the string interning code and use a similar approach.
I don't think parsing the strings is where it spends its time. I think the time is spent in object creation, __format__ lookup, and building the result. I'm looking into some of these other optimizations now.
