Honestly I often put dashes between words that should be grouped together when the parsing might otherwise be ambiguous. It's definitely not a perfect solution (no support for arbitrary nesting, not "standard" English), but it's a bit better for parsing than the German solution insofar as the delimiter isn't an empty string. :)
