So, one thing I'm not seeing obviously in this list of articles (which seem great in general!) is an explanation of how picolisp contrasts to other lisps? Something explaining why I might reach for picolisp instead of, say, scheme or common lisp?

Can anyone share something showing that, or explaining a little bit more about picolisp for someone unfamiliar with it? (I thought the pros/cons list on the page might describe it a little more, but it didn't make things immediately clear to me).

I initially confused this with Lisp for microcontrollers [1]

Gotta admit, the author has a nice sense of eDSL https://picolisp.com/wiki/?taskDB

PicoLisp is like an ancient technology or species which somehow survived to this day. It always felt to me like on the cusp to mainstream acceptance.

No floats, yes, but it has fixnums with infinite precision

I love it, but no floats is a practical limitation.
