 Abstract
 ========
 
-This PEP proposes allowing functions and classes to be decorated with
-any valid expression.
+Python currently requires that all decorators consist of a dotted
+name, optionally followed by a single call. This PEP proposes removing
+these limitations and allowing decorators to be any valid expression.

-Binary Matrix Multiplication
-----------------------------

-One interesting case is the binary ``@`` operator, which was added to
-the language after decorators were first introduced. With the proposed
-change to the grammar, the following decorator expression will be
-unambiguous legal syntax::
-
-    @a @ b
-    def f():
-        ...
-
-However, this pathological case is unlikely to occur in practice, as
-there are no known examples of binary matrix multiplication results
-which may used as decorators. Likely the only people who would do this
-are those who currently write similarly obfuscated toy code::
-
-    @_(a
-    @b)
-    def f():
-        ...
