DeepCompleter

Completions for members of qual's type. These include inherited definitions but not members added by extensions or implicit conversions

Completions for terms and types that are currently in scope: the members of the current class, local definitions and the symbols that have been imported, recursively adding completions from outer scopes. In case a name is ambiguous, no completions are returned for it. This mimics the logic for deciding what is ambiguous used by the compiler. In general in case of a name clash symbols introduced in more deeply nested scopes have higher priority and shadow previous definitions with the same name although:

• imports with the same level of nesting cause an ambiguity
• members and local definitions with the same level of nesting are allowed for overloading
• an import is ignored if there is a local definition or a member introduced in the same scope (even if the import follows it syntactically)
• a more deeply nested import shadowing a member or a local definition causes an ambiguity

Completions for selections from a term. Direct members take priority over members from extensions and so do members from extensions over members from implicit conversions
