Is there anything in the current SRFI draft that says it's a run-time
error?  (I couldn't find it on cursory reading or trying to look for
the appropriate keywords.)  I was surprised by this.  Also, when you
say "doesn't have a value", do you mean:

- doesn't have a binding
- has a binding to some special "unbound" value
- has a binding to a location containing an "unassigned" value

?

Whatever the choice, could you provide a rationale?  It seems odd that
I can use a macro definition in the forms that come after it, but not
a regular definition.  (Right?)
