I see.  Thanks for clarifying.

Well, I'd think we'd want some sort of panic/assert message support,
and if we have that, why not include a line-number option for
all logging?  Maybe it's not always needed, but are there serious
downsides to including it?  Yes, the preprocessor, but is there
anything _else_?  :)

True.  The "flow" of the function call seems kinda weird to me,
but that's probably because I'm used to iostreams.
