Hi Sean,
You can use AnonymousClassInstaller instead of PharoClassInstaller.
Hmmmâ¦ I donât like that. It is for anonymous classes.

We should fix the class builder itselfâ¦ and check that Opal can use environments, too.

It is already on my TODO...
...
We should improve it because it has limitations: the environment is not used and you wonât be able to change the slots or the superclass after creation.
AnonymousClassInstaller make: [ :builder |
  builder
      superclass: Object;
      name: #AClassForTesting ].

I used to have

ClassBuilder new

      subclassOf: Object

      instanceVariableNames: ''
      classVariableNames: ''

      category: 'TemporaryTesting'.
How do I do this with Slots?
I tried:
creatingAClassInATemporaryNamespace
| testingEnvironment morph |
  testingEnvironment := SystemDictionary new.
PharoClassInstaller make: [ :builder |
      builder
      	superclass: Object;
      	name: #AClassForTesting;
      	environment: testingEnvironment;
      	category: 'TemporaryTesting' ].
but got "key #SystemOrganization not found in SystemDictionaryâ.
