Unexpected failure when calling new() with unnamed arg and
Hi,
The man page for new() suggests that if 'a' is an object with slots
"slot1" and "slot2" and C is a class that extends the class of 'a',
then the 2 following calls should be equivalent:
new("C", a, ...)
new("C", slot1=a at slot1, slot2=a at slot2, ...)
This is generally the case but I just ran into a situation where it's
not.

Old-style classes: bug fix & request
...n assignment of class in the base package that
does not break the consistency of classes, we should initialize that
class or classes via a call to setOldClass. The discussion in
"Programming with Data", pp 449-451 covers some of the issues.
The list of old-style classes processed is in .OldClassesList in the
methods package. Elements of the list are character vectors; each is
used in a call to setOldClass during initialization. So elements of the
list with > 1 string define old-style inheritance.
There are a few known classes in the base package NOT currently
initialized:
- "noquote&...
