Feature #10108: NameError#name and nested constants

Hello,

We wanted to bring a discussion around the behavior of NameError#name with nested constants. The result can be quite unexpected when we are dealing with them. For instance:

~~~ruby
begin
  Math::PHI
rescue NameError => e
  e.name # => :PHI
end
~~~

Having Math::PHI seems more expected. Rubinius works the same way as MRI while JRuby will return a symbol with the full path (i.e. `:"Math::PHI"`). Is there any reason why you are returning only the last part of the missing "path" ? At the very least, there is a documentation problem since `NameError#name`'s documentation states:

~~~
name_error.name    ->  string or nil
~~~

but it always return a symbol.

Have a nice day !
