Hi internals,

I have updated the Literal Scalar Types RFC to version 1.0, which I
consider the final revision: https://wiki.php.net/rfc/literal_scalar_types

The changes are editorial, based on feedback in this thread. I merged the
"Accepted literal syntax" section into the per-type sections so each
literal kind is described in one place, added a paragraph to the
introduction on where literal types fit next to enums, tightened the
reasoning in the matching semantics section, and added a short note on enum
comparisons to the Performance section. The proposal itself is unchanged:
the syntax, the semantics and the three votes are the same as in 0.3.

Since this is a minor revision, I am opening voting shortly. A separate
[VOTE] thread will follow.

Thanks to everyone who took part in the discussion.

Seifeddine
