It was either that or libstore. Since I'm about to make it a setting.

Inaccessible-but-extant PATH elements can't be executed anyway, so we
can skip them as if they didn't exist, instead of erroring like before.

In d2696cdd¹, libstore was made to prioritize NIX_BIN_DIR/nix (over
/proc/self/exe) if it exists. But `pathExists()` throws an exception if
lstat() returns any error other than non-existence.
Because this check happens in libstore's Settings constructor for the
static-initialized global `nix::Settings`, this case would abort Lix
well before main().

Meson conveniently does lets you pass feature objects to `required :`

This fixes Meson's "Project does not target a minimum version but uses
feature introduced in '1.1': meson.options file" warning.
Silly Meson.
I also added a note in the top-level meson.build to indicate

This documents that all installables in the nix3 commands, in their
--file/-f form accept an extended syntax for the file argument,
which is the same as it is for nix-build and friends, some of which were
well known in their nix-build forms (e.g. `nix-build '<nixpkgs>' -A hello)
but are not well known in their nix3 forms (people rarely know that you
can `nix build -f '<nixpkgs>' firefox`).
Like the old CLI syntax, as documented in [1], file arguments also
accept https:// tarball URLs, `flake:` prefixed flakerefs, and the
cursed `channel:` prefixed hardened URLs.

This documents the fact that nix-build, nix-env, nix-instantiate, and
nix-shell accept an extended syntax for their file arguments, including
some well-known (but not well documented) aspects, like being able to
specify `<nixpkgs>`, but also https:// tarball URLs, `flake:` prefixed
flakerefs, and the cursed `channel:` prefixed hardcoded URLs

Lix commit 4dbbd721e[1] changed the way settings are changed, removing

DrvInfo's constructor that only takes `EvalState` leaves everything else
empty; a DrvInfo which has no iota of information about the derivation
it represents is not useful, and was not used anywhere.

This commit adds a new helper template function to gc-alloc.hh (which is
probably where you want to look at first, O great reviewer [custom file

The purpose of this function has little to do with immutability. Value's
strings are never mutated, and the point of this function is to
singleton empty strings.

DrvInfo's query methods all use mutable fields to cache, but like.
that's basically the entire interface for DrvInfo. Not only that, but
these formerly-const-marked functions can even throw due to eval errors!
Changing this only required removing some `const` markers in nix-env,
and changing a single inline `queryInstalled()` call to be an lvalue
instead.
