I think these should be in their own library called "string", then  
each of the objects would in individual objects in that library:  
[string/join], [string/split], etc.  "flatspace" is not the place for  
it, that's for backwards compatibility.  I think that the syntax of  
[list] is inconsistent without adding anything useful.  Everywhere  
else in the core of Pd, the object class is always is the first name,  
and the rest are arguments.
