+Subject: [PATCH] Fix invalid fastcall dict when keywords are passed
+
+Fixes #5665
+
+I'm slightly surprised this hasn't caused more bugs. We're passing
+a dict where we should be passing a tuple of names.
+
+Replacement should hopefully be right, but I don't know how
+optimized or otherwise it is.
