For now, in commit 92423868bc451600f8f3d93b638091d12b14b7aa, I’ve
arranged so that auto-compilation is turned off for Guile 2.2.3 only.

At the same time, I reverted the offending change in Guile, and
hopefully we’ll release 2.2.4 shortly:

  https://debbugs.gnu.org/cgi/bugreport.cgi?bug=29226#25

I’m not sure we can do much better for 2.2.3, or perhaps we should
always use (compile-file file #:to 'value) in ‘load*’?

Thanks,
Ludo’.
