(j3.2006) finalizer infelicity

I agree with Bill on this one :-)  By the way, there is no constraint even 
saying a compiler must diagnose this situation if subroutine S is called 
directly (not via finalizer): call S(X1).  Without explicit interface, 
this call is not something can be diagnosed.

Sorry. Too late for that.  We should not, buy the interp process, 
introduce new constraints that turn conforming programs into 
non-conforming programs.  Interps are for interpretations of what the 
standard means.  Not for "oops, we changed our minds and want different 
rules now".  This is not a case where the existing rules are unclear. 
And there are enough compilers available that support final routines 
that this is not a theoretical discussion.
