[O] [babel] Using :prologue and :epilogue with unbalanced brackets

Hi

I would like to use :prologue and :epilogue to enclose the code block
in a local({}) block, i.e.

* test
#+begin_src R :prologue local({   :epilogue })
qwerty <- "test"
#+end_src

But the problem seems to be the unbalanced brackets, and everything is
passed on as the prologue, as I get the error:

Error: unexpected ':' in:
"{
local({  :"
Execution halted

Can I somehow use unbalanced brackets, or is this a missing option in
epilogue and prologue?

Cheers,

Rainer
