Yes, that's a good suggestion.

Just to be clear, do you consider the following to be an inline block?
 (I usually think of inline as limited to src_R{ ...} type things).
Or are you generally talking about the distinction between #+begin_src
/ #+end_src lines vs #+call lines?

#+begin_src R :results output raw replace :exports results
 cat.fname.link()
#+end_src

Finally, in the last file of my original message I try to use #+call's
everywhere instead of source blocks.  Cleaned up example is pasted
below.  It looks broken (the first #+call bar is out of order, the
second and third #+call bar's don't run), see
http://pastebin.com/LqYK0Ps2 with my annotation where the output looks
broken

----------snip---------
#+property: session *R-babel*

#+NAME: foo
#+HEADER: :var a="a1.png"
#+BEGIN_SRC R :results output silent
  cat("in foo block\n")
  cat.a <- function() { cat(a,"\n",sep="") }
  cat.a()
#+END_SRC

#+NAME: bar
#+begin_src R :results output raw replace :exports none
 cat.a()
#+end_src


Should have all a1 stuff

#+call: foo(a="a1.png")

#+call: bar()

Should have all a2 stuff

#+call: foo(a="a2.png")

#+call: bar()

Should have all a3 stuff

#+call: foo(a="a3.png")

#+call: bar()
