Detailed Description

AST Node for a compilation unit.

The Unit AST node is the owner for all AST nodes in the unit. This node maintains two namespace hierarchies

• the root namespace is the namespace for all types defined in this unit
• the import namespace is the namespace for all types imported into the unit from other modules.
