A very reasonable test for guile 'master' (guile 3.0.5) is to use it during 
building of lilypond and its documentation.

Building guile 'branch_release-1-8' is currently broken, it says it requires 
autoconf 2.71 but it does not build with that version. I used a slightly older 
version of guile 1.8 that still works with autoconf 2.69:

      exec git checkout 618620c4c8a52705d27439bb1f2bc505629c640a in 
/home/knut/sources/guile ... succeeded after 0 seconds
      exec git reset --hard in /home/knut/sources/guile ... succeeded after 0 
seconds
      exec git clean -dfx in /home/knut/sources/guile ... succeeded after 0 
seconds

      exec ./configure --disable-error-on-warning

Building guile 'master' is easy but really slow now. Autoconf 2.71 is required:

      exec git checkout master in /home/knut/sources/guile ... succeeded after 
0 seconds
      exec git reset --hard in /home/knut/sources/guile ... succeeded after 0 
seconds

seconds

      exec ./configure --disable-error-on-warning

      GUILELIBDIR is /home/knut/sources/lilybuilt/share/lilypond/lib64
      exec make -j 16 in /home/knut/sources/guile ... succeeded after 716 
seconds
      exec make -j 16 install in /home/knut/sources/guile ... succeeded after 1 
seconds
   *GUILE build time: 768 seconds*

Building lilypond 'master' with guile 1.8 (commit 618620c) succeeds as expected:

Building lilypond 'master' with guile 'master' looks promising:
