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
