Subject [GitHub] metron issue #687: METRON-1090 Add Assignment to Stellar Language
Date Thu, 18 Jan 2018 20:36:08 GMT
Github user mattf-horton commented on the issue:

    https://github.com/apache/metron/pull/687
  
    If one insists that ':=' in Enrichments is a Metron add-on not Stellar, that is equivalent
to stating that Enrichment doesn't use Stellar but rather a custom DSL derived from Stellar.
 The xml stuff wrapped around Stellar by Profiler, Enrichments, etc, can reasonably be viewed
as external to Stellar, but the ':=' token is clearly part of the Enrichment DSL.  
    
    The ':=' token is also part of the Stellar REPL, which again we've wrapped with caveats
that it's got additions to Stellar that aren't part of Stellar.
    
    Sure quacks like a duck to me, but if it's not a Duck then it's a non-Duck, according
to Aristotle :-)
    
    Fact is, to any user not immersed in implementation details, it's part of Stellar.  Why
don't we be nice and make it all uniform?
