Description

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:

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 !
