When there's too much nesting, and therefore too many braces, consider 1) refactor out inner nestings into new methods 2) label }'s:

namespace foo
{
public class bar
{
public void fu()
{
for(var int i = 0; i < 10; i++)
{
if(Math.PI != 0.0)
{

            } // if PI not 0

        } // for i

    } // fu

} // bar

} // foo
