Exploring picolisp

I'm looking at picolisp -- and wondering how it works, or better, why it
doesn't really work work with babel. First problem, I couldn't get any form
of picolisp to work in Emacs -- until I stopped starting Emacs with

emacsclient -c -a ''

which sets up my daemon first. Got abstruse error -- and it creates a file
called `editor-orig` in `~/.pil` which blocks any further attempts. After
tearing stuff out of my init diaspora for hours, I finally found that a
straight

>emacs &

made picolisp-mode work, otherwise, not. Very weird. But then I see this
<https://github.com/tj64/ob-picolisp> and, yes, picolisp babel seems to
work for all the examples. However, a regular function declaration

#+name: hello
#+begin_src picolisp
(de hello (X)
   (prinl "Hello " X) )
#+end_src

-- goes nowhere. But then C-c C-c in a picolisp code block isn't firing up
a REPL, so where can it go? Nowhere. Lisp, Scheme & Cie. all require a
running REPL that org-mode knows about. And if I just bring up
picolisp-mode with a picolisp file and fire up a REPL, that REPL doesn't
know anything about my org-mode picolisp code blocks.

I don't mean to complain or sound negative, but picolisp as is can't really
be included as a babel language, can it? Maybe it worked once, but doesn't
now?
