+  * Consider ctxsw optimization:
+    - In backend, prefix parameter names (in assignments and expansions) with TU
+      and function
+    - In eshrt, remove variable updating code
+    - Caveat: breaks variable parameter names in eval
+    - If arrays are implemented, would anyone still need variable parameter
+      names?
+    - Maybe add -fno-mangle-vars option to eshtrans to disable prefixing and
+      insert a flag in generated code to enable eshrt to update variables
