Comment(by burcin):

 I uploaded new versions of the two old patches, rebased to 4.3.1.rc0, and
 a referee patch. I consider this ready now, though someone needs to review
 my changes.

 Unfortunately attachment:trac_6465-chain_rule.take2.patch depends on the
 next version of pynac. I will release that real soon now. :)

 The patches should be applied in this order:
  * attachment:trac_6465-chain_rule.take2.patch
  * attachment:trac_6465-moves-integration-into-sfunction-
 subclass.take2.patch
  * attachment:trac_6465-integral.patch

 They probably depend on other tickets. ATM, my queue contains: #7822,
 #6961, #7876, #7363, #7955, #7957, #7916 related to symbolics.
