This took longer than I wanted, mainly because I ended up wrapping the TCL C API to make it play more like pyo3.

But yeah, you can now run Python directly *inside* of TCL, next step is to better do Python -> TCL interop.

After that, you can call a Python script that can drive Vivado :v

I added common lisp to the startup shutdown bench.
From the fastest to slowest: true ngnk dash luajit lua bash sh awk perl zsh jq gprolog tclsh bun bqn sbcl chicken fish poly clisp bb guile php python js78 js60 node ocaml deno ruby scryer ghc julia R erl racket swipl clj

I added racket to my startup+shutdown time comparison.

Okay, kinda hacky tcl <-> py interop, no actual object interop yet, but I need lunch and I think the brainworms ran out
A screenshot of terminal over a text editor, inside the text editor is the Python code: from snek import run_tcl run_tcl('puts "lmao"") And then in the terminal in the front is a tclsh shell with a module loaded, then the command `py run "/tmp/nya.py"` and the output "lmao"

Added raku to the startup+shutdown overhead comparison. It has much more overhead than perl and even ruby.
From smallest overhead to largest: true ngnk luajit dash lua bash sh zsh awk perl jq tclsh gprolog bqn bun sbcl chicken-csi fish poly clisp bb guile php python js78 js60 node ocaml deno ruby scryer-prolog ghc rakudo julia R erl racket swipl clj
