Re: [racket-dev] syntax-property guards? (was: Re: The Stepper strikes again)

[Matthias Felleisen]

Eli is right in principle. I sense that we are facing the same kind of problems 
we faced when we created mixins and then again when we created continuation 
marks.  We need annotations time and again and they couple parts of our system 
more closely than necessary. Problem is, we don't seem to see or have an 
abstraction that eliminates this coupling.
