Subject: Re: Dynamic Methods

somthing like:

def method_missing(name, *args)
  meths = instance_methods +
	  private_instance_methods +
	  protected_instance_methods
  re = Regexp.new("(#{name}.*)[;]")  
  md = re.match(meths.join(';'))
  send(md[1], *args) if md
end

essentially it looks at all the methods available and finds a match then
uses send to call it.

this is not tested, but should work along these lines. could also be
made a little more concise.
