After my initial pass through Ex7, I had 2 thoughts:

1. The depth of thought and analysis that is going into the Perl 6 design.

   Given that formats are (or rather were) seen as a little-used, oft-deprecated, obscure & archaic feature of perl 5, that the redesign should have produced such a comprehensive replacement says something.

2. The Perl 6 Language Reference Manual may need to come on a DVD rather than a CD:)
