Yes, but it still doesn't mean you should hide the braces (in the
inferior languages) on other lines.

I have trouble with that too.  My preference (FWIW, probably nothing) :

if ( some_condition() )
{
    for (i = first_i();i <= 10; i++)
    {
        initialize_some_stuff();
        while ( some_other_condition() )
        {
             do_some_more_stuff()
        }
    }
}


Notice how the matching braces are horizontally aligned and at the
same level as the line that initiates the bock?  If the braces are
removed, and colons added it will look like python (with some
extraneous parens).

This is hard for me because I can't see what the '}' goes with.
Combine this with leaving out the braces on one-line compound
statements, and I'll have real problems.
