this is admittedly more like the c++ version,
and is very easy to implement using method_missing.

but really i'd suggest that whatever is chosen is
natural to ruby, easy to convert from the equivalent 
c++, and applicable to both dcop and non dcop signals.

not really sure i like this syntax, and its pretty
difficult to implement :) - you need to do a temporary
override on the blocks method_missing. which is
probably possibly knowing ruby, but i've not idea
how to do so :)
