This PR was rebased onto a different master commit. Here's a range-diff highlighting what actually changed. Rebasing is a normal part of keeping PRs up to date, so no action is needed—this note is just to help reviewers. |
I can't really think of a good place to put this, but it didn't really fit with the rule it currently was in.
This more or less repeats what is already said in layout.repr.alignment.intro where it explains that they are modifiers that affect a representation.
This consolidates the rules for how repr values can be combined. This adds a few previously undocumented combinations, and I think all permutations should now be covered.
