+Subject: [PATCH] Store the universe of known types in an ordered BTreeSet
+ (#374)
+
+The set of types is used in multiple places during FFI creation. When
+the data structure does not guarantee the order of elements, such as
+HashSet, the resulting generated source code is not deterministic. Using
+a BTreeSet resolves this issue by providing a well-defined element order
+over which the the set may be iterated.
