* MacOS build
* Windows build
* clang-on-Linux build
-* Multi-arch testing
- - non-x86_64 images lack installed cpanminus and don't enable caching.
- ppc64le builds seem unreasonably slow to install CPAN deps each time

- - Testing support for arm64.
* Use containers for non-Ubuntu-based Linux testing
-* E-mail notifications
* VPATH builds
* sanity checks for use of APLOGNO() - empty arguments, accidental duplicates, etc.
- not sure how exactly
+* Known test failures
+ - "apt-get install" timeout/fails - workaround by moving apt install to before_script phase?
+ - t/apache/expr_string.t - unclear root cause, possible workaround in r1872705
+ - t/apache/rwrite.t, t/apache/pass_brigade.t
