Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Exec(Spanned<SmallVec<[UnescapedString<'a>; 1]>>)

Exec-form (JSON array)

Shell(Spanned<&'a str>)

Shell-form (space-separated string or here-documents), escape preserved
