How to handle python for loops

[maximiliankaul]

I'm not sure how to best map python for loops to CPG. Let us first consider the simple case:

for item in items:
  ...

The item can either be a previously defined Variable (and thus a DeclaredReferenceExpression in the CPG or a new variable (and thus a VariableDeclaration). Correct?

Python for loops get a bit trickier than this (https://docs.python.org/3/library/ast.html#ast.For), but I'm right now stuck with how to model the simple case item as in the example above...
Any ideas @oxisto @konradweiss

Just discussed this with oxisto: I will look into extending the ForEachStatement to also hold an nodeTarget Expression.
Additional idea: items could maybe be modeled as an Unary Operator
