Probably a missed left over from somewhere in
the commit 58f385f680.
As can be seen in that commit where this line was introduced,
"$@" was also just emptied by the last `set` call in line 169.
This line is currently valid, but breaks suddenly when somewhere earlier
a `set --` instruction is used in the future.
Neither in commit 58f385f680
nor in PR https://github.com/NixOS/nixpkgs/pull/197547
have I found anything stating that this "defect" was intentional.
`For android 'sdkVer' has been renamed to 'androidSdkVersion'`
While doing the above rename I forgot to consider if there were still
darwin platforms in `lib.systems.examples` using `sdkVer`
These still fail eval, but that happened before the renaming too.
`error: Unsupported sdk: 14.3`
In preparation for the deprecation of `stdenv.isX`.
These shorthands are not conducive to cross-compilation because they
hide the platforms.
Darwin might get cross-compilation for which the continued usage of `stdenv.isDarwin` will get in the way
One example of why this is bad and especially affects compiler packages
https://www.github.com/NixOS/nixpkgs/pull/343059
There are too many files to go through manually but a treewide should
get users thinking when they see a `hostPlatform.isX` in a place where it
doesn't make sense.

This makes the type more informative and general - closer to how the function behaves, particularly in isolation.

Previously, for values of type list, the merge function would only retain the value
if the number of option definitions was less than or equal to 1, and would throw an
error for conflicting definitions to avoid potentially unwanted list merges.
This change removes that logic, defaulting to the 'mergeEqualOption' function for
values of type list. This approach maintains the same safeguard against merging
different lists while allowing lists with identical values to be merged.
Mesa is a package like any other. There's no reason for it to be a
special case with its platforms listed in lib, because if other
packages want to refer to mesa's platforms, they can access the
platforms from the package meta like they would for any other package.
