If an implementation "proclaims the variable special" but then admits no
constructs where that proclaimation has an affect, then the result is an
internal detail.
I think the issue is: Is it legal to attempt to lexically rebind a variable
that has been defined with DEFCONSTANT, as might be implied by the wording
on p. 69, and the Proposal is No, it is not, and the Current Practice is
"Most implementations don't allow this."
