Hmm.. I missed that. At first, I though than remove() behaviour should be  
consistent with opIn(), i.e. it should return a pointer to a value, but it  
is not possible.

Looks like the best guess is to return the stored value or T.init, if no  
value is found (i.e. null for ref types and some default value for value  
types).
