See the attached file for an example of working property inheritance.
#+Property: EMAIL address@hidden
* Contact Name
:PROPERTIES:
:EMAIL+: address@hidden
:END:
#+begin_src emacs-lisp
(org-entry-get (point) "email" 'inherit)
#+end_src
#+results:
: address@hidden address@hidden
* Contact Name
:PROPERTIES:
:FOO: 1
:FOO+: 2
:END:
#+begin_src emacs-lisp
(org-entry-get (point) "FOO" 'inherit)
#+end_src
#+results:
: 1
While it is not possible to accumulate two properties from within the
same block, property accumulation does successfully add to the inherited
values of variables.
I don't know if it should be possible to accumulate properties within
the same property block. I would imagine so, in which case the behavior
should be considered a bug.

FALSE, the "var" property is in no way special when it comes to property
inheritance. All properties are treated equally.
