Is there any way to do literate Babel-style things with eshell? Only shell
(sh) seems to be listed among the languages. As I understand, eshell is
just a wrapper around actual elisp expressions. For example,

find-file foobar.txt

is actually

(find-file "foobar.txt")

I'd like to do shell-like stuff and capture everything literate-style in
code and result blocks. If no Babel for eshell, is there a way to translate
eshell into its raw elisp? Then I could do Babel on the elisp.
