I agree with this statement, but not with the interpretation that you wish to enforce.

What declaration? What block? These constructs have clear
syntactic definitions and the case you describe does not match
those definitions. Any parsing past the unexpected character is
really just guessing on the part of the parser.

If you write a new syntax, we will at least have some basis from
which to consider dropping the old core syntax, despite the
latter's promise of indefinite longevity and stability.
