Re-read the decorator PEP: http://www.python.org/peps/pep-0318.html to
understand why both of these options (indentation and prefix notation)
are undesireable for a general decorator syntax.

The desire for context managers to have access to its enclosing scope is
another discussion entirely, though it may do so without express
permission via stack frame manipulation.
