    @ottobackwards And yet this discussion primarily relates to whether the 
assignment operation as defined in Enrichment should be unified with the 
assignment operation being added to core stellar, presumably due to user demand.

> 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.
