 Returns a new parser for the given string *specifier*. The specifier string may contain the same directives as [*locale*.format](#locale_format). The `%d` and `%e` directives are considered equivalent for parsing.
 
 The returned function parses a specified *string*, returning the corresponding [date](https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Date) or null if the string could not be parsed according to this format’s specifier. Parsing is strict: if the specified <i>string</i> does not exactly match the associated specifier, this method returns null. For example, if the associated specifier is `%Y-%m-%dT%H:%M:%SZ`, then the string `"2011-07-01T19:15:28Z"` will be parsed as expected, but `"2011-07-01T19:15:28"`, `"2011-07-01 19:15:28"` and `"2011-07-01"` will return null. (Note that the literal `Z` here is different from the time zone offset directive `%Z`.) If a more flexible parser is desired, try multiple formats sequentially until one returns non-null.

Subject: [PATCH 2/5] deliberate ES6 syntax

(rationale: don't let people install @3 in a build system that will not alert them that we have moved to ES6, only to cause trouble with a later release.)
