So, I was wrong when I initially looked at this PR, this adds variable
updates to the resolver. Should we perhaps separate parsing assignments (e.g.
move `StellarAssignment.from` into the language like you've done here) from
actually updating the variables. I think I'd like to see Enrichments and the
REPL refactored to not hand-code the variable update logic when we get around
to updating the resolver to allow updates. Thoughts?

> Project: Metron
> Issue Type: New Feature
> Reporter: Otto Fowler
> Assignee: Otto Fowler
> Priority: Major
>
> Add support for =, +=, -=, *=, /= for variables in stellar.
> foo = 5 returns 5 AND sets foo to 5 if the VariableResolver supports it.
> The shell should be changed to assign variables using this syntax, because
> exposing the left side to stellar allows catching errors for invalid keywords
> in left side.
