ghc GHC.Core.Map.Type A BndrMap is a TypeMapG which allows us to distinguish between binding forms whose binders have different types. For example, if we are doing a TrieMap lookup on (x :: Int) -> (), we should not pick up an entry in the TrieMap for (x :: Bool) -> (): we can disambiguate this by matching on the type (or kind, if this a binder in a type) of the binder. We also need to do the same for multiplicity! Which, since multiplicities are encoded simply as a Type, amounts to have a Trie for a pair of types. Tries of pairs are composition.
