1039       * Tag a template literal string for localization.
1040       *
1041       * For example:
1042       *
1043       * ```ts
1044       * $localize `some string to localize`
1045       * ```
1046       *
1047       * **Providing meaning, description and id**
1048       *
1049       * You can optionally specify one or more of `meaning`, `description` and `id` for a localized
1050       * string by pre-pending it with a colon delimited block of the form:
1051       *
1052       * ```ts
1053       * $localize`:meaning|description@@id:source message text`;
1054       *
1055       * $localize`:meaning|:source message text`;
1056       * $localize`:description:source message text`;
1057       * $localize`:@@id:source message text`;
1058       * ```
1059       *
1060       * This format is the same as that used for `i18n` markers in Angular templates. See the
1061       * [Angular 18n guide](guide/i18n#mark-text-for-translations).
1062       *
1063       * **Naming placeholders**
1064       *
1065       * If the template literal string contains expressions, then the expressions will be automatically
1066       * associated with placeholder names for you.
1067       *
1068       * For example:
1069       *
1070       * ```ts
1071       * $localize `Hi ${name}! There are ${items.length} items.`;
1072       * ```
1073       *
1074       * will generate a message-source of `Hi {$PH}! There are {$PH_1} items`.
1075       *
1076       * The recommended practice is to name the placeholder associated with each expression though.
1077       *
1078       * Do this by providing the placeholder name wrapped in `:` characters directly after the
1079       * expression. These placeholder names are stripped out of the rendered localized string.
1080       *
1081       * For example, to name the `items.length` expression placeholder `itemCount` you write:
1082       *
1083       * ```ts
1084       * $localize `There are ${items.length}:itemCount: items`;
1085       * ```
1086       *
1087       * **Escaping colon markers**
1088       *
1089       * If you need to use a `:` character directly at the start of a tagged string that has no
1090       * metadata block, or directly after a substitution expression that has no name you must escape
1091       * the `:` by preceding it with a backslash:
1092       *
1093       * For example:
1094       *
1095       * ```ts
1096       * // message has a metadata block so no need to escape colon
1097       * $localize `:some description::this message starts with a colon (:)`;
1098       * // no metadata block so the colon must be escaped
1099       * $localize `\:this message starts with a colon (:)`;
1100       * ```
1101       *
1102       * ```ts
1103       * // named substitution so no need to escape colon
1104       * $localize `${label}:label:: ${}`
1105       * // anonymous substitution so colon must be escaped
1106       * $localize `${label}\: ${}`
1107       * ```
1108       *
1109       * **Processing localized strings:**
1110       *
1111       * There are three scenarios:
1112       *
1113       * * **compile-time inlining**: the `$localize` tag is transformed at compile tim
1113e by a
1114       * transpiler, removing the tag and replacing the template literal string with a translated
1115       * literal string from a collection of translations provided to the transpilation tool.
1116       *
1117       * * **run-time evaluation**: the `$localize` tag is a run-time function that replaces and
1118       * reorders the parts (static strings and expressions) of the template literal string with strings
1119       * from a collection of translations loaded at run-time.
1120       *
1121       * * **pass-through evaluation**: the `$localize` tag is a run-time function that simply evaluates
1122       * the original template literal string without applying any translations to the parts. This
1123       * version is used during development or where there is no need to translate the localized
1124       * template literals.
1125       *
1126       * @param messageParts a collection of the static parts of the template string.
1127       * @param expressions a collection of the values of each placeholder in the template string.
1128       * @returns the translated string, with the `messageParts` and `expressions` interleaved together.
