Name the parameters single_element_container and three_element_container, as that's relevant to the caller. Then we can rename the local copy to just `writable`, which avoids wrapping lines.
MSVC emits a probably-unjustified signed/unsigned warning if we attempt to directly initialize _Int_max. Since we're intentionally changing the type from int to size_t, it seems stylistically best to emphasize this with a static_cast anyways.

I still prefer almost always auto in a lot of these cases, but I know that's not the style of the standard library, so approve.

We conventionally avoid the pattern
auto variable = Type{args};because it is strictly more complicated thanType variable{args};. Following this convention reservesautofor the cases where it's doing real work to deduce a type.We've accumulated a few cases which I'm cleaning up here. (There are a few more cases which I am reluctantly not changing, because
autoresults in code lining up nicely. I thought about it, though.)In
P2321R2_views_zip, I'm also performing some renames. We can name the parameterssingle_element_containerandthree_element_container, as that's relevant to the caller. Then we can rename the local copy to justwritable, which avoids wrapping lines.In
<__msvc_int128.hpp>, I'm usingstatic_cast. MSVC emits a signed/unsigned warning if we attempt to directly initialize_Int_max(possibly becausenumeric_limits::max()isconstexprbut notconsteval). Since we're intentionally changing the type frominttosize_t, it seems stylistically best to emphasize this with astatic_castanyways.
