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.
