Hi Mikhail,

The code block name is not a member of params.  Params only holds header
arguments, not other meta data like the name.  The code block name is
stored in the `info' list which is active while the code block is being
processed, so you could access it with something like the following,
although which is relying on an implementation detail that is not part
of the formal spec (i.e., cheating) and could change.

#+name: foo
#+begin_src emacs-lisp
  (nth 4 info)
#+end_src

#+RESULTS: foo
: foo

Best,
