Hello all,
The code below is not legal (problem with the foo_t initializer list)
because:
"A reference that is not to 'const' cannot be bound to a non-lvalue"
How can I best achieve an effect similar to what this code attempts?
Thanks,

I need to be able to keep a list of object references, and null them out one
by one at a later point in time. I realize this can be dangerous, but I have
my reasons.
I can't figure out, however, how to keep what is essentially a reference to
a reference. I want to store my objects in an ArrayList, then loop through
the array list and null...

Hi,

I have been trying out boost's serialization library for the past few
days. And I have come across a problem serializing a class that has a
reference member. The code is posted as below:

This post was originally in the C# Corner site, but their server is
down. I'd like to see if this group can answer.

list, when, after all, it appears in C# that for...
