I'm glad this sparks interest in improving the error message display, this is good. I can't say I'd accept something given the handwavy description, you'll need to create examples of how it would look.

One thing I have noticed while doing this is how unhelpful many of the error messages are. Consider the first one in traits.d:

        error(loc, "size overflow for type `%s`", t.toChars());

What was the size, and what was the maximum size? The compiler has this information, but does not supply it in the message.

This is all low hanging fruit that anyone can help with.
