---------------------------+------------------------------------------------
Extend sage.misc.fpickle.pyx with a PicklableFunction class wrapping
interactively defined (simple) functions to make them picklable:
{{{
sage: f = lambda x: x^2
sage: loads(dumps(f))
------------------------------------------------------------
Traceback (most recent call last):
File "<ipython console>", line 1, in <module>
File "sage_object.pyx", line 792, in
sage.structure.sage_object.dumps (sage/structure/sage_object.c:8357)
PicklingError: Can't pickle <type 'function'>: attribute lookup
__builtin__.function failed
sage: f = PicklableFunction(f)
sage: f(3)
9
sage: f == loads(dumps(f))
True
}}}
