Subject: method overloading like Java?

In Java, you could write the following code:
public void foo(int x)
{ /* do something*/ }

public void foo(String x)
{ /* do something*/ }

int x1
String x2

foo(x1)
foo(x2)

The 2nd to last line would call the first foo and the last line would 
call the 2nd foo.

Is there a way to do this in Ruby?  I am aware of method(*args) and 
case...when but I think Java's version is cleaner and more readable.  I 
also know that variables in Ruby are dynamically typed, the method that 
is called should be based on the most recent type of the variable being 
passed.

I don't want to do this:
def foo(arg)
if arg.type_of? String
	# do something
elsif arg.type_of? Numeric
	#do something
else
	raise args error
end
end

thanks,
Dan
