I would expect that an implementation in this direction would transform
error ("there is no operator %E with arguments %T and %T", foo, bar, baz)
into an internal IL rich enough to represent formatting directives
(and "2D" representation) independent of the actual rendering device's
capabilities.
It would then be up to each output device to display the diagnostics based on
their own characteristics (color or not, caret or not, pointing the cursor back
to the source file or not). And indeed, it would be really terrible idea if the
intelligibility of a diagnostic -requires- colors.
