Just had a short glance on the API of MapMaker. My impression is that it 
is out of scope for [lang] as it is a full blown collection with many 
sophisticated features.

Compared to this a Memoizer is a pretty simplistic component, but it may 
nevertheless be useful for some cases. It could be slightly extended, 
e.g. by providing a flush() operation.

And I would recommend another name. At least for me as non-native 
speaker it is hard to imagine what a Memoizer is supposed to do. I would 
probably use something with "Cache" in its name.
