* Implemented the ==' and !=' operators. These now use a deep
...
equality test, so they also work for (finite) attribute sets and
lists.

* Quick and dirty implementation of with'. with e1; e2' is
...
basically desugared to `let <with> = e1; e2', and `lookupVar' looks
in each <with> in the environment chain for an attribute with the
specified name.

* Simplify @-patterns: only {attrs}@name' or name@{attrs}' are now
...
allowed. So `name1@name2', `{attrs1}@{attrs2}' and so on are now no
longer legal. This is no big loss because they were not useful
anyway.
This also changes the output of builtins.toXML for @-patterns
slightly.

...
instead of (memoised) call-by-name.
