 There is?  Completely forgot about that.
 
 If I recall the big wish list item I had for your serializer was
 robust subclass handling for things like serializing a BaseClass[]
 with a mix of pointers to BaseClass and DerivedClass.  You need to be
 able to de-serialize that by saying something like
 unserialize!(BaseClass[]).  I think at the time I tried it, your
 serializer didn't save enough info to know the proper derived class to
 load up.

This is still missing. The problem I had is that template functions are not
virtual, so I can not get derived class which should be dumped. But I think it
can be doable: just needs some more time and thinking. Now typeid() gives type
of most derived class, so maybe this is a way?

Well, it was definitely possible, even a year ago, because Tom S.'s
serializer in xf could do it, though I don't recall how. It was quite
complicated.   Layers and layers of ctfe code instantiating templates
creating more code via ctfe, or something like that.

 Now typeid() gives type of most derived class, so maybe this is a way?


Yeh, definitely seems like that could help.
