- [nitpick] The new static error message may reduce context for debugging. If dynamic error details are useful, consider reintroducing a parameterized variant to capture more specific information.

I've rewritten all the GNU testcases of
gnu/tests/expr/expr.plin our testsuite, to more easily track potential regressions.Sadly, the remaining issues are all caused by our regex dependency (
rust-onig) which has a diverging behavior from GNU. This emphasizes the need to find another regex engine, as discussed in #1145
