Major:
- more verbose error messages (ie: which argument is wrong, and why)
- "delete" support - in order drop references?
- collection class is read-only presently - make read-write
- Review the bindings for "curve" and consider changes based on Kst changes
- line and arrow orientations don't fully work
- bezier doesn't work


General Completion:
- input and output map for data objects
- events and possibility to define event handlers


Would be nice:
- save and load state
- object browser GUI
- multiple interpreters?
- dump list of loaded files
- many bindings lack good [or any] bindings (ComboBox, list{view,box}, etc)
- string comparisons are too slow - at least use ustring


Docs:
- Add examples with an example node
- Make it pretty
