So a bunch more comments came in while I was writing the above. Nick's
comment about enrichments using assignment already of course modifies my
comment about Profilers, etc. Just making it uniform would give users a lot

As for := vs =, it's not so terrible to have both as exact synonyms. This
gives you both your preferred aesthetics and backward compatibility.---
