No, it shouldn't. You may implement function bodies in other modules

Right, but it just feels wrong to me for constructors & destructors
since they are a required part of the class. Either you implement one or
you don't, but simply declaring one without an implementation feels like
an error to me.
Without this feature, .di files wouldn't work. The advantage is that
functions without bodies are faster for the compiler to parse, when it
it's not going to compile them anyway. You can also use it for hiding
implementation, if you don't want your source to be available.
