(This is really for Raymond, though I'm replying to Guido's post.)

I'm having a hard time understanding why this matters.  Maybe I'm just
dense on a Sunday morning.

Can you explain what makes it difficult to debug about keyword
arguments if they are held in a normal dictionary?  Debugging at the
Python level or the C level? Can you give an example where it would be
easier to debug?  If it makes it easier here, would it make it easier
to debug other dictionary usage if they were ordered?
