Picolisp has "native" calls as an FFI to call C shared libraries from
Picolisp, and build Picolisp wrapper functions on top of C functions
defined in header files.
A lot of programming languages allow that, there are e.g. many Python
wrappers for all kinds of data science libraries. But with
So, if I understand correctly we could use the introspective power of
picolisp and write a {meta?}program to produce the "library" for Pil, and
then use this to call R from picolisp?

Hi Alex,
after digging deeper in R Internals I found out that there are actually C
access functions for the various subtypes of SEXP that can be wrapped with
native too:
rinc: (setupRinC)
-> NIL
rinc: (evalQuietlyInR "V <- c(1.5, 3.4, 4.2)")
-> NIL
rinc: (evalInR "V")
-> 65007640
rinc: (REAL
Hi all,
for other programming languages there are sandbox tools to edit, run and
share code snippets, which one would like to show or discuss.
Like replit.com or one of the many webdev sandboxes like jsfiddle.net.
I wanted to ask if someone knows sth similar for picolisp.
But thanks to
