*** 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.

** TODO Remove protective commas from # comments before evaluating
org inserts protective commas in front of ## comments in language
modes that use them. We need to remove them prior to sending code
to the interpreter.
** PROPOSED conversion between org-babel and noweb (e.g. .Rnw) format
I haven't thought about this properly. Just noting it down. What
Sweave uses is called "R noweb" (.Rnw).
