KangarooTwelve is a family of two fast and secure extendable-output
functions (XOFs): KT128 and KT256. These functions generalize
traditional hash functions by allowing arbitrary output lengths.
KangarooTwelve was designed by SHA-3 authors. It aims to deliver
higher performance than the SHA-3 and SHAKE functions defined in
FIPS 202, while preserving their flexibility and core security
principles.
On high-end platforms, it can take advantage of parallelism,
whether through multiple CPU cores or SIMD instructions.
As modern SHA-3 constructions, KT128 and KT256 can serve as
general-purpose hash functions and can be used, for example, in
key-derivation, and with arbitrarily large inputs.

It seems to me this was simply forgotten.
Or there is some reason I don't know why this code doesn't work for `comptime_float`.
For a more comprehensive fix, https://github.com/ziglang/zig/pull/24057 is the place to look.
This method is called on an identifier token, so let's rename the parameter to make this clear.
This is also how it's named on most of the caller's sides.
This also unifies the rename implementations, since previously `posix.renameW` used `MoveFileEx` while `posix.renameatW` used `NtOpenFile`/`NtSetInformationFile`. This, in turn, allows the `MoveFileEx` bindings to be deleted as `posix.renameW` was the only usage.
This functionality -- if it's actually needed -- can be reintroduced through
some other mechanism. An ABI is clearly not the right way to represent it.

This is not the only test that aborts like this, nor does it happen only on
FreeBSD, but it happens to be disproportionally disruptive on FreeBSD in
particular.
The new builtins are:
* `@EnumLiteral`
* `@Int`
* `@Fn`
* `@Pointer`
* `@Tuple`
* `@Enum`
* `@Union`
* `@Struct`
Their usage is documented in the language reference.
There is no `@Array` because arrays can be created like this:
if (sentinel) |s| [n:s]T else [n]T
There is also no `@Float`. Instead, `std.meta.Float` can serve this use
case if necessary.
There is no `@ErrorSet` and intentionally no way to achieve this.
Likewise, there is intentionally no way to reify tuples with comptime
fields, or function types with comptime parameters. These decisions
simplify the Zig language specification, and moreover make Zig code more
readable by discouraging overly complex metaprogramming.
