Hello,

Excuse me. I have some questions to ask you.

1. Do you need to add multiplication, division and remainder operations in operations module?

like this:

defmultiplication(field,n):deftransform(doc):doc[field]*=nreturntransform...

2. whyupdate andpop methods oftinydb.utils.FrozenDict write like this? Is it becauseupdate andclear are different?

update=_immutablepop=_immutable

3. You can replacelink1 andlink2 tocollections.OrderedDict.move_to_end() function, inget andset methods oftinydb.utils.LRUCache.
