--- Comment #2 from Serhei Makarov <me at serhei dot io> ---
Making some progress (as of commit be31be3ff) but there are a number of
glitches to work out, e.g.:
- exit() in a probe still causes output to be swallowed (PR23435).
- error() weirdly does not print anything.
- assert() with a nested call to error() causes an invalid eBPF program to be
generated.
