Up to this part was very understandable and agreeable, but I was

... this conclusion.  I somehow thought that t-basic part would be a
good test-tool subcommand, as it is run from the suite of shell
scripts for end-to-end testing CLI interaction.

Do we have any precedent to place programs placed under t/tXXXX/ and
get them compiled?

And this motivation is very much understandable, and for that, as
long as it is outside t/unit-tests/, it would be good.  I just did
not expect it to hang under t/t0080/, inviting more unit test pieces
that are triggerable from the numberd shell scripts to hang under
random t/t[0-9][0-9][0-9][0-9]/ directories.
