+# Strict mode to disallow ignoring returned values
+
+This ties in to the last point.  In Scheme, a non-tail expression in a
+body can return an arbitrary number of values, which will be silently
+ignored.
+
+This can lead to bugs, where a procedure actually returns some kind of
+success or failure indicator (instead of raising an error) and the
+programmer forgets to handle it.
+
+Though it may be too inefficient to enable globally, there should at
+least be a mode of compilation that emits code which checks at every
+single function return whether there are any values that are being
+ignored, and raises an error if so.
+
+There would of course be a form to explicitly ignore values.
