The smiley indicates that you know
that I mean new potential test writers
compared to the language choice. Right now many will have the learn TinyScheme
or at least the details of TinyScheme compared to other scheme schemes.
(SCNR). You are restating the problem.

Okay, it is online here https://mitpress.mit.edu/sicp/,
but sorry this is not a modern tutorial nor a good documentation

I am refering to TinyScheme in particular, I know that there is a significant
community in Scheme dialects. However when writing tests I will probably rely
on some of the finer details of this particular implementation.

Created 1993, from https://www.lua.org/about.html
//The tarball for Lua 5.3.2, which contains source code and documentation,
takes 282K compressed and 1.1M uncompressed. The source contains around 24000
lines of C. Under 64-bit Linux, the Lua interpreter built with all standard
Lua libraries takes 245K and the Lua library takes 419K. //
Compare this to TinyScheme, to be fair I include the reg exp and date
54k Mai 4 15:56 re-1.3.tar.gz
62k Mai 4 09:00 tinyscheme-1.41.tar.gz
8,5k Mai 4 15:55 tsx-1.1.tgz
okay, that is ~125k, half the size of the lua tarball.
sloccount gives me almost 10k lines of code,
so lua is only about a factor of 1.4 as large as TinyScheme.

You mean because guile-2.0.11.tar.gz is 7.3 MiByte large?
Yes, that is ~25 times as large as lua.
Or because it it too young and fasionable (created 1995)?

Doing an example command session, including the git checkout and separation
against potential existing gnupg installations will really enable some more
