RE: Dylan Constants

Do the Program Constants (p20) not suffice for this? $pi, $end-of-file, $etc.

Is the problem in first paragraph of Variable names on p20: "the names 
of variables do not affect the semantics of the program"?

Does Dylan raise an error on (set! $pi 3.0)?

 From the Dylan reference, there appears to be now way of defining a read
only constant ala the Common Lisp DEFCONSTANT macro. This appears to be an
omission since that *constantness* of a variable is helpful to both
programmers and compilers.

Given a choice, I'd vote for an extension to the syntax of the DEFINE form
rather and the addition of another DEF macro.

Any thoughts?
