I found that using stack dumps unconditionally can get very confusing -- 
especially if there is a lot of output and if you use it in multiple 
places at the same time or in loops. So I've switch to some form of 
stack assertion where I specify what I think the top-most elements of 
the stack should look like, and the stack contents only get dumped when 
the actual stack contents are different.

What also helps is the source file name, line number, and function name 
where the stack dump is from (`__FILE__`, `__LINE__`, and `__func__` (or 
`__FUNCTION__` for MSVC)).

p.s.: About the braces thing: I prefer one-statement control structures 
without the braces because of vertical space. I use a lot of split 
windows and vim buffers, and

    if( something )
    {
      do_something();
    }

is twice as long as the alternative.
