Yet another variant that deals with "passive" metadata: make the first 
dictionary special just like the first string.

>>> def foobar():
...     { author = "van Rossum",
...       deprecated = True }
...
>>> foobar.deprecated
True

Even better, stash it all away in a another attribute:

>>> foobar.__meta__
{"author": "van Rossum", "deprecated": "not yet"}

This would work for both functions and classes. Fitting in nicely: the 
alternative spelling for all dictionaries:

{alpha="value", beta="another value"}
