I am curious if there is a programatic way to list all methods of a class.
(Yes, I know about "ri", I am just curious here)

For instance, I am trying to figure out what I could do with the File f in:
open(ARGV[0], 'rb') { |f|
  puts f.stat.mtime
  puts f.class
}

Now, f.class returns: File

Is there anything like:
  f.functions.each { |p| puts p }

Thanks
