[Alexandria-list] New bug... sorry

[LJD]

Worked it out, although I don't understand quite what this means.

I commented out your 

alias_method :old_select, :select
        def select
           filtered_library = Library.new(@name)
            self.each do |book|
                filtered_library << book if yield(book)
            end
            return filtered_library
        end

method in alexandria/library.rb and everything went back to normal. I
don't understand enough ruby - I guess alias_method a way of overriding
the default select method of the Array class? If so, what's wrong with
select returning an array?

I'm curious!

Gonna have to clean up my code before my version drifts too far from
CVS.
