[C++-sig] question on object section of bpl tutorial

[Mark Russell]

Hi Dave,

A quick question from the basic interface page of the object portion of the
bpl tutorial.  On this page you show the following code snippet.  What types
are x & y?  --Mark

def f(x, y):
	if (y == 'foo'):
		x[3:7] = 'bar'
	else:
		x.items += y(3, x)
	return x
