Re: [pbmserv-dev] my moultezim program is buggy. help!

[John Williams <williams@morinda.com>]

Looking in lists.cpp, I see that Init merely copies the pointer, but the =
operator makes a full copy of the values, so this should work.

IntList old;
old.Init().Add(1).Add(2).Add(3);
IntList new;
new = old;

It's OK to change the original board array in order to test things, as
long as you put it back when you are done.  HexEmergo::NextLegalMove and
Chess::IsMate do this, but not recursively.  Recursing should not be a
problem though.
