Expand Properties and Constants on constants where it makes sense

[Crell]

Should we go further and apply the same to enum cases?

Edit: Wait, no, we didn't bother making them compacted because no one uses that style. Ignore me. 😄

This makes sense to me. I also think it makes sense to expand the underscore is meaningless directive to include all constructs including variables and enum cases and anything else anyway.

[Crell]

That makes sense. @samdark, can you expand the wording a bit?

1. The section is "4.3 Properties and Constants" so variables and other constructs do not fit there.
2. Underscore is typically used in foreach ($items as $key => $_item) to indicate that only key is needed.

Valid. OK, let's proceed here.
