Hmm, so this is an interesting one. We sorta have a de facto assignment
outside of stellar, but I'd be interested in having it moved into stellar like
this. I'd also be sorta ok with it being `=`, but we chose `:=` earlier, so
that is an open question as to whether it should be consistent.
Also, it seems like processing a stellar statement should return 2 things
now:
1. the output value
2. optionally a variable assigned
We should also refactor the `StellarAssignment` class to use this somehow.
Other than that, this seems extremely promising!
