It wouldn't be too difficult. Ragel is only used to parse the text form of 
uuids. As that's a pretty simple task, such a parser could be written 
manually.

But I also have a almost complete HTTP header parser/formatter 
implementation using ragel which I wanted to propose for phobos eventually. 
And I'm not going to rewrite those, so I hoped std.uuid could clear the way 
for ragel based code in phobos ;-)
