Redefining hat operator for Proc

[bparanj]

Hello,

I am developing a gem where I need to redefine the <=> operator for
Proc. This operator shows up in the methods list when I print the
output of methods call but I don't see it in the list of private or
protected methods.

I know in Ruby 1.9 === operator has been redefined, but I am not able
to confirm that <=> is currently implemented in Ruby 1.9. I don't want
to over-ride the hat operator if it is already implemented for Proc.
Could someone please give me some pointers?

TIA.
Bala

If you do Proc.instance_method<=>), what do you get? If nil, then
it's not overridden.

irb(main):005:0> p = Proc.instance_method<=>)
NameError: undefined method `<=>' for class `Proc'
from (irb):5:in `instance_method'
from (irb):5
from /usr/local/bin/irb:12:in `<main>'

Looks like it is safe to redefine it. Thanks.
