And jolie2plasma for the tool that does the opposite of course! :-]

Yeah I think too that message type checking would be a nice feature in general 
when using the Plasma::Service API; well, we can use JOLIE types "manually" to 
gain it when using JOLIE adapters, but that's clearly not an optimal solution. 
Anyway, we can always put it in the future without compromising anything. =)
