[pclasses-devel] suggestions for SimpleApp and AboutData

[stephan b. <st...@s1...>]

Yo again!

i'm working on re-implementing eshell on top of P (pshell, of course), 
and i've come across a couple usability problems:

- AboutData cannot be default-constructed. This means i can't currently 
deserialize it because i cannot classload it without installing a 
factory which creates a bogus one by passing invalid info to the ctor.
This change implies that various mutators have to be added, like 
copyright(string), etc.

- Having non-const overloads of the list<> accessors would make 
de/serialization a snap:
serialize_subnode( mynode, "authors", this->about().authors() );
deserialize_subnode( mynode, "authors", this->about().authors() );


- SimpleApp also can't be default constructed. Same prob as above: can't 
classload it without adding a completely bogus factory, plus creating a 
bogus AboutData to pass to that object's ctor.
Also, how about a protected:
	AboutData & about();
(non-const)

so that subclasses can modify/serialize that object.

Are these feasible?
