+*** need to evaluate header arguments whenever we switch to *Org Edit Src* buffer
+    Another thought on this topic: I think we will want users to send chunks
+of code to the interpreter from within the *Org Edit Src* buffer, and I
+think that's what you have in mind already. In ESS that is done using
+the ess-eval-* functions. That seems to imply that the header references
+need to be evaluated and transformed into the target language object
+when we hit C-c ' to enter the *Org Edit Src* buffer (or at least before
+the first time we attempt to evaluate code in that buffer -- I suppose
+there might be an argument for lazy evaluation, in case someone hits C-c
+' but is "just looking" and not actually evaluating anything.) Of course
+if evaluating the reference is computationally intensive then the user
+might have to wait before they get the *Org Edit Src* buffer.
