Expected `[` after `IN` keyword.

Expected only comma-separated field names inside `IN[..]` but instead found `> 2]`.

Expression `\'blue, green` is missing the following closing delimiter: `'`.

insta::assert_display_snapshot!(p!("x = EXISTS"), @r###"
Was expecting a value but instead got `EXISTS`, which is a reserved keyword. To use `EXISTS` as a field name or a value, surround it by quotes.

Was expecting a value but instead got `AND`, which is a reserved keyword. To use `AND` as a field name or a value, surround it by quotes.
