In C++, it's largely the namespace, which is being used ever more.

Instead of writing

    namespace foo {
    int bar (int baz)
    {
        .....
    }
    .....
    }

, people are indenting within the namespace, something like

    namespace foo {
        int bar (int baz)
	{
	    ....
	}
	....
    }

.  Not all the time, but a lot of the time, possibly most of the time.
This indentation inside a namespace seems like a natural way to format a
program, and people are going to carry on doing it.

The issue is how we best deal with this.
