##1.downto(1) {|i| puts i}
##=> 1
##
##1.downto(2) {|i| puts i}
##=> 1
##
##Is this right? The block is always executed once, even when
#the limits
##would suggest otherwise? 1.upto(0) does the same thing...
#
#imho, yes.
#so for start.downto(limit), it may never get to the limit but
#it always gets to start.
#
#are you thinking something like,
#
#start.downto(limit){|i| puts i} if start>=limit
#
#if yes, you can modify downto or create own downto.
#
#something like,
#
#:0> class Fixnum
#:1> def downto(limit=self)
#:2> super if self>=limit
#:2> end
#:1> end
#=> nil
#
#:0> 3.downto(1) {|x| puts x}
#3
#2
#1
#=> 3
#:0> 3.downto(3) {|x| puts x}
#3
#=> 3
#:0> 3.downto(4) {|x| puts x}
#=> nil
