I think that a statement like C<< $x = 1 if my $x; >> ought to complain. Put slightly differently, if it's an error in any of the compilers, it probably should be an error in all of them. > If it's required to complain, then the parser need to remember all > such uses and check it against declaration later, and it'd be better > to say that in the spec instead. 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.
