// Slice range bound markers — same matrix as for-header ranges: each side
// of `..` takes `=` (inclusive) or `<` (exclusive), defaults 0-inclusive
// start / exclusive end. Prefix form takes markers too ([..=2], [<..3]);
// [..] is the whole slice; bounds are arbitrary expressions; strings slice
// through the same path.
