Metamodel:: roles missing

[taboege]

The problem

The HOW types, look for instance at EnumHow, do a lot of roles and not all of them are documented, as can already be seen from them not appearing in the table of contents of the HOW type.

• Metamodel::Documenting
• Metamodel::Stashing
• Metamodel::Mixins
• Metamodel::MultiMethodContainer
• what else?

Suggestions

Complete the list above and then document them. I suppose that the line between "documentable" and "utter implementation detail" is especially thin here, so that might have to be decided on a per-case basis. I would argue that Documenting and MultiMethodContainer are documentable.

Seems to be a continuation of #1306
