Why is that?  Will this be fixed, or is this the intended design?

That's obvious.  No one will argue the contrary.

But is there a reason not to follow the CL design in general wrt the
cohabitation of lexical and dynamic binding?  Even if things are currently
a work in progress, is that the direction you intend to head, or are you
aiming elsewhere?

Is there a description somewhere of where the design is headed in this
regard?  Is there a spec or a proposal?  What are the intentions?

There was a lot of discussion behind the CL design.  What are the proposals
here and their supporting arguments?
