I too had been scratching my head about the use of the dotted notation

Hello, I've recently stumbled across Picolisp (while playing around with
Termux) and have been reading up and finding it very intriguing. In the
process of learning, I experimented with making a function to generate

I tried doing a local install of picolisp in my Chromebook's Linux

After downloading and building the 19.12 tarball, I find that the pil
script in picoLisp/bin has /usr/bin/picolisp as the shbang, so it
wouldn't actually work as a local installation.

I've been digging down to really understand the symbol implementation in
Picolisp, since symbols are used for so many purposes within the language.
One surprising thing I learned last night is that (get ...) has a side
effect! It moves the key that was accessed to the head of the symbol

"Prepend", aka "add to the beginning" seems the natural (and

I'm experimenting with the object system in Picolisp, and I'm wondering
if there is a way of teaching the REPL to invoke some formatting
function when displaying an object instance? Having to constantly invoke

tedious...
