It’s a requirement because the evaluation process has side effects on
the Guile that runs it; for instance, it loads tons of modules in it.
Also, the evaluation process may need to load modules that have the same
name as currently-loaded modules, but different content—and Guile
supports only one module with a given name.

That said, this program should be moved to $libexecdir/cuirass/VERSION.

HTH,
Ludo’.
