yes

#+PROPERTY: var foo=2
#+PROPERTY: var+ 5

#+begin_src emacs-lisp
  foo
#+end_src

#+results:
: 25

I think by types you mean something more like syntactic parsing?  Babel
does have three types, strings, numbers, and lists.

Keep in mind that the above applies to *all* Org-mode properties, not
just variables, which is why I did not want to force an assumed comma
separator.

For example,

#+PROPERTY: Disks  1 2 3 4 5 6 7
#+PROPERTY: Disks+ 8 9 10 11 12 13

#+begin_src emacs-lisp
  org-file-properties
#+end_src

#+results:
| (var . foo=25) | (Disks . 1 2 3 4 5 6 78 9 10 11 12 13) |

Although in this case the 78 is certainly unexpected.  Perhaps inserting
an assumed space separator would be more intuitive?  If we were to go
that way it may be possible to allow variable specifications such as

#+PROPERTY: var foo=1 bar=2

in which case properties could be easily specified on multiple lines
using a default space separator.

If this seems like a good way to go I can try to update my previous
patch.
