I've been checking respond_to? before calling send() for ages but today
its failing in a simple case.

I define a method outside of a class or module. send() works but
respond_to? fails. You could define a method in irb and check for
respond_to?

Where are these methods getting defined if not in Object?

Here's a snippet you can try:
---

#!/usr/bin/env ruby

def testme
  puts "inside testme"
end

if respond_to? :testme
  send :testme
else
  puts "sorry"
end

---
I just tried out "defined? :testme" and that works, but I'd still like
to know which is better to use, and why respond_to fails.

thx
rahul
