I don't understand, either.  The braces do nest, but I don't know what 
the "computation of matching brace" problem is.

This test currently passes in my implementation:
         self.assertEqual('{0[{bar}]}'.format('abcdefg', bar=4), 'e')

This shows nesting braces working.  Bill, what problem are you thinking of?
