+A frame-local binding is actually a frame parameter value.
+If a frame F has a value for the frame parameter named VARIABLE,
+that also acts as a frame-local binding for VARIABLE in F--
+provided this function has been called to enable VARIABLE
+to have frame-local bindings at all.
+
+The only way to create a frame-local binding for VARIABLE in a frame
+is to set the VARIABLE frame parameter of that frame. See
