//META: purpose=Boundary - a multi-character delimiter (`long`) on a raw string opens with `R"long(` and closes only at `)long"`.

// Boundary probe: the documented raw-string rule uses an "arbitrary"
// delimiter. A four-character delimiter is exercised here. The string
// content includes a `)` and a `)w` substring that resemble a close
// for shorter delimiters but must NOT terminate this token.
