AttributeError for rdfSingle

[cakebread]

I like how rdfMultiple raises an AttributeError if I try to pass in a
non-list.

Could we get rdfSingle to do something similar if we try to pass in a
list or tuple? That doesn't cover all incorrect types, but would cover
the most common mistakes.

Something like:

+++ descriptors.py (working copy)
@@ -145,6 +145,10 @@
def __set__(self, obj, value):
log.debug("SET with descriptor value %s of type %s"%
(value,type(value)))
#setattr(obj, self.name, value) #this recurses indefinatly
+
+ if isinstance(value, list) or isinstance(value, tuple):
+ raise AttributeError("to set an rdfSingle you must pass
in a single value")
+

Thanks Rob,
Put this in changeset: 116

also updated rdfMultiple (and descendants) to allow a list or a tuple
(not just a list).
