I generally agree with you.  Especially because I believe sooner or later we will regret all lowercase because we find that sometimes the best accessor names are a bit too long to be comfortable with all lowercase (even 3 or 4 short words would be uncomfortable in all lowercase IMO).  I would at least like to see this get more discussion before it is settled.

This means, for example, that dynamicType already has the correct case even though it is a keyword.  I would like to see this exemption added to the proposal.

If we agree on lowercase for user-defined accessors (which is Chris’s stated preference) I support the change to willset and didset.
