if you're quoting the example correctly, I'm pretty sure this template
constructor has no purpose at all, since it is not a copy-constructor
(no template constructor is), and one specialization of class complex
does not have access to fields `re' and `im' of any other
specialization thereof.

It really does, but, unless I've missed some important part of the
standard, a specialization of a template class does not implicitly
gain priviledged access to another specialization of the same template
class.
