I think that a statement like  C<< $x = 1 if my $x; >> ought to

Put slightly differently, if it's an error in any of the compilers,
it probably should be an error in all of them.

I think that S04's phrase "then it's an error to declare it" 
indicates that this should always be treated as an error.  How/when
the compiler chooses to report the error is up to the compiler.  :-)
That said, I wouldn't have any objection to removing or altering
"the compiler is allowed to complain at that point" phrase so
as to remove this particular ambiguity.
