Hi,
I needed a strict version of insertWith on IntMaps in one of my projects. I added both insertWith' and insertWithKey' for consistency with Data.Map.
I didn't bump the version number as I assume this is done just before release rather by the first patch that mandates an increase according to the PVP. Since this is an API addition the third version number should be bumped.
Who applies patches to containers?
