digitalmars.D.learn - Filling up a FormatSpec

Is there any way to parse a format string into a FormatSpec? FormatSpec has a private function "fillUp" which is not accessible. I need to provide formatting capabilities to a custom data type, I've already written the standard function: void toString(C)(scope void delegate(const(C)) sink, FormatSpec!C fs) const but I want to provide another function: string toString(C)(const(C) fmt) and forward it to the standard one. The problem is that initializing FormatSpec with fmt does not parse it: auto fs = FormatSpec!C(fmt); //this will just put fmt in fs.trailing I know that I can use format() for this, but I don't want to import 6000 code lines, I would prefer to interpret myself FormatSpec once parsed.
