Sorry, @ottobackwards this got lost in the shuffle. What I was saying was
that I think we should not adjust the VariableResolver infrastructure to update
variables as the result of assignments, but rather return back the variable and
the updated object. For instance, in the `BaseStellarProcessor` class we have
a `parse` method that returns the output of the expression. I'd suggest we
have a `parseExpression` and `parseAssignment` where the first acts as it does
now and the second returns the variable name and the result. As a follow-on, I
think we can adjust the variableresolver infrastructure to support variable
updates.
I guess ultimately, I suggest a tactical solution that leads us to the
right direction rather than trying to fix it all at once.
Thoughts?
