Perl 6 Design Documents

The Synopsis documents are the design documents used to guide Perl 6 language, compiler, and test development. As design documents, they're frequently subjected to the rigors of cross-examination through implementation and use in practice. In other words, they may change slightly or radically, but the expectation is that they are ``very close`` to the final shape of Perl 6.

In the past the Synopses have often been referred to as "the formal Perl 6 specification" and "specs", but this usage is being deprecated in favor of treating tests from the "roast" test suite as official specifications. This is consistent with Synopsis 1, which says "Perl 6 is anything that passes the official test suite."
