Yes, `hasContext e` should work where `e` is a contextful strings, otherwise, it is really useless.

`test-generator` has not been updated in the past 2 years.
`rstest` has not been updated in the past 5 months.
This is an improvement in the maintenance state… I guess?
We get also new features, it changes the name of the tests with numbers too.

We want to handle bottoms in a consistent fashion. Previously this was
handled by repetitive is_catchable checks, which were not consistently

Nix does something like:
```cpp
NixStringContext context;
const auto str = state.forceString(*args[1], context, pos, "while evaluating the second argument passed to builtins.split");
```
And then do nothing with that context, therefore, we follow them and
make `split` aware of the context but still do nothing with it.

r/7176 introduced an incorrect assumption was the benefit of the
nonrecursive coercion algorithm, namely that a coercion operation always
returns a non empty string. This allows to detect whether we are
coercing a list or not by checking if the intermediate result is empty
or not. Unfortunately, coercing null and false yields an empty string,
so we need to explicitly track whether we are coercing a list.
Updated the test case to hopefully catch similar bugs in the future. I'm
not a hundred percent certain I have not introduced a new edge case with
this, so it may be interesting to add a prop test case for this to
nix_oracle down the line. At least lists are the only nested data
structures that can be serialized as nested data structures, so the
problem is kind of limited.

The default behavior of string coercion in C++ Nix is to weakly coerce
and import to store if necessary. There is a flag to make it strongly
coerce (coerceMore) and a flag that controls whether path values have
the corresponding file/directory imported into the store before
returning the (store) path as a string (copyToStore). We need to
implement our equivalent to the copyToStore (import_paths) flag for the
benefit of weak coercions that don't import into the store (dirOf,
baseNameOf, readFile, ...) and strong coercions that don't import into
the store (toString).
This makes coerce_to_string as well as CoercionKind weirder and more
versatile, but prevents us from reimplementing parts of the coercion
logic constantly as can be seen in the case of baseNameOf.
Note that it is not possible to test this properly in //tvix/eval tests
due to the lack of an appropriate EvalIO implementation being available.
Tests should be added to //tvix/glue down the line.

This matches the behavior of C++ Nix more closely where the decision is

Note that this doesn't make a difference in any successful
evaluation (at least to my knowledge), but ensures that our error
messages will match C++ Nix more closely, e.g. in the case of
`1 + "string"`.
