+Subject: [PATCH 1/2] First take at GHC 9.* compatibility.
+
+There's a lot here that can be cleaned up, and we need
+some backward compatiblity layer, but this is just a first
+try.
+
+Something in the PrimeEC module is causing hard crashes
+during the test suite, so I'll have to figure out what's
+going on there.
