+ * @param {String} pattern XRegExp pattern using `{{name}}` for embedded subpatterns. Allows

+ *   leading `^` and trailing unescaped `$` are stripped from subpatterns, if both are present.
+ * @param {String} [flags] Any combination of XRegExp flags.
+ * @returns {RegExp} Regex with interpolated subpatterns.
+ * @example
+ *
+ * var time = XRegExp.build('(?x)^ {{hours}} ({{minutes}}) $', {
+ *   hours: XRegExp.build('{{h12}} : | {{h24}}', {
+ *     h12: /1[0-2]|0?[1-9]/,
