#+title: Scope of properties as variables for babel blocks

* Overview

I have the following scenario in mind: =func1= and =func2= are two

functions that can be executed in two modes: =foo= and =bar=. Each

mode yields a different set of results, that have to be discussed,

separately, in two different subtrees.

The goal is to have one subtree where they are executed in one mode

and a second subtree for the other mode.

The functions are defined in a dedicated [[Code][subtree]].

* Bar setting

Now, I want to execute the function in =bar= mode:

#+PROPERTY:  var mode="bar"

#+CALL: func1()

#+RESULTS:

: default

#+CALL: func2()

#+RESULTS:

: default

* Foo setting

In this node I want to execute  the functions in =foo= mode:

#+PROPERTY:  var mode="foo"

#+CALL: func1()

#+RESULTS:

: default

#+CALL: func2()

#+RESULTS:

: default

* Code

#+name: func1

#+begin_src python

return mode

#+end_src

#+RESULTS: func1

: foo

#+name: func2

#+begin_src python

return mode

#+end_src

#+RESULTS: func2

: default-val

* Question:

How can I implement this kind of workflow in a reproducible org mode document?
