Here we're switching to combinators instead of dereference operator.
It turns out the dereference operator was being executed upon test
setup, meaning that we were only using a only single value for each of
the executions of the property tests! Really not good.
And on Windows, we instead get:
operator* is not allowed in this context
ff6af6fc68/src/gen/detail/GenerationHandler.cpp (L16C31-L16C71)
Now a few of the property tests fail, because we're generating cases
which haven't been exercised before.
Fix a footgun. In my case, I had a couple of build ("output")
directories sitting around.
rm -rf build-*
Was confused for a bit why a meson.build file was missing.
Probably also helps with autocompletion.
I tried meson-build-support first, but I had to add something like
a nix- prefix, in order to make meson happy. They've reserved the
meson- prefix.
Since lib{expr,store,util}-test-support subprojects define nix_api_* helpers
for testing nix c bindings, they need to publicly depend on -c counterparts.
This makes their headers self-sufficient and does not rely on the -tests to add
necessary dependencies.
This reduces the amount of boilerplate. More importantly, it provides
a place to add compiler flags (such as -O3) without having to add it
to every subproject (and the risk of forgetting to include it).
