Thanks for the feedback, Vincente.

Yes, a scoped_indent would help.  I think the extra --
was put in there just to show nothing bad would
happen.  IOW, the indententation never goes
below 0.

I've used something like a scoped_indent to trace
code.  It's called trace_scope, which is attached.
The mout() is actually an earlier version of the code
which didn't use the iostreams library, but works
similar to the proposed code (except mout() couldn't
be converted to basic:ostream&).

-regards,
