 * `%h<>` now means `%h{}` -- the entire hash, not the empty string as key

 * Implemented staleness checking for .yml/.pm loader
-* The following code is no longer allowed:

-        my $x = 2;

-* "role A does A" is not allowed anymore
-* "my $x; { $x; my $x }" now fails with a sensible error message
 * Allow $::x to mean exactly the same as $x
-* "sub ($x = 0 is copy)" is invalid; say "sub ($x is copy = 0)" instead
 * Pugs.Parser: $() now means $$/, @() means @$/, %() means %$/, etc
 * Added identity values for the builtin reduceable operators from S03
 * Implement hyperfold and hyperscan: [>>+<<] and [\>>+<<]
-* Unicode support for the embedded Perl5 bridge.  (This takes effect iff
-  the embedded Perl supports SvUTF8_on, typically Perl 5.8+.)
-* Pugs.Parser: Support for attribute call syntax
-    @.foo(1, 2, 3);     # self.foo(1,2,3).'@'

-* Much improve multi dispatch system
-* Implement quantified method calls: $obj.*meth, $obj.+meth, $obj.?meth,
-  as well as quantified dynamic method calls: $obj.[+*?]$meth
-* User-defined macros now take effect even in prefix unary
-  and optional unary
-* "Odd numbers of elements in hash" is now made fatal
-  (it was not even a warning) to help shake out incorrect
-  usages of things like 1<2>
-* Pugs.Prim.Keyed: Instead of allowing "1.delete();" to return undef,
-  we now simply fail
 * Pugs.Eval: Autovivification is now constrainted by typed variables:

-* "sub f ($x is lazy) {...}" is now guaranteed to not evaluate

 * Switch chained comparison such as "1 > 2 > die('not reached')

-* Fix expected outut of head-neck-tail in examples/:

-* Fix take [1,2,3]" shouldn't flatten into "take 1,2,3

-  substr instead of copying string
-* ".perl" now returns Unicode strings properly
