/**
* Tag a template literal string for localization.
*
* For example:
*
* ```ts
* $localize `some string to localize`
* ```
*
* **Providing meaning, description and id**
*
* You can optionally specify one or more of `meaning`, `description` and `id` for a localized
* string by pre-pending it with a colon delimited block of the form:
*
* ```ts
* $localize`:meaning|description@@id:source message text`;
*
* $localize`:meaning|:source message text`;
* $localize`:description:source message text`;
* $localize`:@@id:source message text`;
* ```
*
* This format is the same as that used for `i18n` markers in Angular templates. See the
* [Angular 18n guide](guide/i18n#template-translations).
*
* **Naming placeholders**
*
* If the template literal string contains expressions, then the expressions will be automatically
* associated with placeholder names for you.
*
* For example:
*
* ```ts
* $localize `Hi ${name}! There are ${items.length} items.`;
* ```
*
* will generate a message-source of `Hi {$PH}! There are {$PH_1} items`.
*
* The recommended practice is to name the placeholder associated with each expression though.
*
* Do this by providing the placeholder name wrapped in `:` characters directly after the
* expression. These placeholder names are stripped out of the rendered localized string.
*
* For example, to name the `items.length` expression placeholder `itemCount` you write:
*
* ```ts
* $localize `There are ${items.length}:itemCount: items`;
* ```
*
* **Escaping colon markers**
*
* If you need to use a `:` character directly at the start of a tagged string that has no
* metadata block, or directly after a substitution expression that has no name you must escape
* the `:` by preceding it with a backslash:
*
* For example:
*
* ```ts
* // message has a metadata block so no need to escape colon
* $localize `:some description::this message starts with a colon (:)`;
* // no metadata block so the colon must be escaped
* $localize `\:this message starts with a colon (:)`;
* ```
*
* ```ts
* // named substitution so no need to escape colon
* $localize `${label}:label:: ${}`
* // anonymous substitution so colon must be escaped
* $localize `${label}\: ${}`
* ```
*
* **Processing localized strings:**
*
* There are three scenarios:
*
* * **compile-time inlining**: the `$localize` tag is transformed at compile time by a
* transpiler, removing the tag and replacing the template literal string with a translated
* literal string from a collection of translations provided to the transpilation tool.
*
* * **run-time evaluation**: the `$localize` tag is a run-time function that replaces and
* reorders the parts (static strings and expressions) of the template literal string with strings
* from a collection of translations loaded at run-time.
*
* * **pass-through evaluation**: the `$localize` tag is a run-time function that simply evaluates
* the original template literal string without applying any translations to the parts. This
* version is used during development or where there is no need to translate the localized
* template literals.
* @param messageParts a collection of the static parts of the template string.
* @param expressions a collection of the values of each placeholder in the template string.
* @returns the translated string, with the `messageParts` and `expressions` interleaved together.
*/
