Subject [GitHub] metron issue #687: METRON-1090 Add Assignment to Stellar Language
Date Thu, 18 Jan 2018 16:25:08 GMT

    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!
