No, P6 was intended to fix as many Perl 5 problems as possible, and being eminently parseable was considered very important (and important in deciding to forsake backwards-compatibility, I believe). In fact, a key design-goal is having the language defined by a well-formed grammar that it actually uses to parse itself — and thus that can be used by tools such as editors to parse it just as easily.
