PER-CS 3.1 target list

[Crell]

With PHP 8.5 coming out very soon, it's time for a minor update. This should not require any breaking changes, so I expect it to be a 3.1 release, not 4.0.

Issues I've seen discussed are listed below. Discuss further in those issues/PRs. If you want to take a crack at one, please do, but put your name next to the issue in the list below and/or say so in the issue thread so we don't duplicate work.

New functionality

• PHP 8.5: Always require parentheses around clone() #124
• Clarify binary operators generally, including pipe #127
• Forbid use of semi-colon on switch case/default statements #128 / switch case and default must not have semicolons #129
• Add an example for closure with an empty body #133

Existing clarifications

• Clarify that commas should always have spaces after them, even in arrays. (Destructuring syntax (list() and []) #119)

There are some occurrences in PER-CS where it refers to itself as "This PSR". These occurrences should be changed to "This PER", it's minor but no harm in addressing this.

Hm, nice catch. Can you make a separate issue for it, or better yet a PR to change it to "this standard"?
