> If you construct a variable which returns a map in a stellar enrichment, it is not able to be used in statements afterwards due to the fact that we explode the map.
> For instance:
> {code}
> foo := { 'foo' : 7}
> foo_num := MAP_GET('foo', foo)
> foo := null
> {code}
> would yield the following fields:
> * {code}foo.foo == 7 {code}
> * {code}foo_num := null {code}
> What we would prefer is just:
> * {code}foo_num == 7{code}
> As a policy, we should only explode the fields which are maps that are around at the end of the enrichments.  Also, the map itself should be available to be used in downstream enrichments.
