the next outer context that makes visible further implicits
refs
the implicit references made visible by the current context.
Note: The name of the reference might be different from the name of its symbol.
In the case of a renaming import a => b, the name of the reference is the renamed
name, b, whereas the name of the symbol is the original name, a.
The level increases if current context has a different owner or scope than
the context of the next-outer ImplicitRefs. This is however disabled under
Scala2 mode, since we do not want to change the implicit disambiguation then.
