Subject: strange warning

Folks:
I get this warning message when I run the code below.  What am I doing wrong
here?

<<C:/ruby/lib/ruby/1.7/tk.rb:196: warning: default `to_a' will be obsolete>>

#----------------------from this code-------------------------
require 'tk'
# testing callback code for listbox

cb = nil
lb = TkListbox.new.pack
1.upto(3){|v| lb.insert('end',"entry #{v}")}
lb.bind('ButtonRelease-1'){cb.call lb.get(lb.curselection[0]) if cb}


cb = proc{|v| p v}
Tk.mainloop
#------------------------------------------------------------

Thanks,
Alan
