-// After toml post-v0.5.0, it is explicitly clarified how quotes in ml-strings
-// are allowed to be used.
-// After this, the following strings are *explicitly* allowed.
-// - One or two `"`s in a multi-line basic string is allowed wherever it is.
-// - Three consecutive `"`s in a multi-line basic string is considered as a delimiter.
-// - One or two `"`s can appear just before or after the delimiter.
-// ```toml
-// str4 = """Here are two quotation marks: "". Simple enough."""
-// str5 = """Here are three quotation marks: ""\"."""
-// str6 = """Here are fifteen quotation marks: ""\"""\"""\"""\"""\"."""
-// str7 = """"This," she said, "is just a pointless statement.""""
-// ```
-// In the current implementation (v3.3.0), it is difficult to parse `str7` in
-// the above example. It is difficult to recognize `"` at the end of string body
-// collectly. It will be misunderstood as a `"""` delimiter and an additional,
-// invalid `"`. Like this:
-// ```console
-//   what():  [error] toml::parse_table: invalid line format
-//  --> hoge.toml
-//     |
-//  13 | str7 = """"This," she said, "is just a pointless statement.""""
-//     |                                                               ^- expected newline, but got '"'.
-// ```
-// As a quick workaround for this problem, `lex_ml_basic_string_delim` was
-// splitted into two, `lex_ml_basic_string_open` and `lex_ml_basic_string_close`.
-// `lex_ml_basic_string_open` allows only `"""`. `_close` allows 3-5 `"`s.
-// In parse_ml_basic_string() function, the trailing `"`s will be attached to
-// the string body.
