The problem is that you can't do this in generic code, because
generic code by definition doesn't know how to copy an

I'm not familiar with that definition of generic code. But I do
feel that there's a pretty big problem with a language design
if the language doesn't provide a generic way to make a copy of
a variable. To be fair, e.g. C++ doesn't provide that either.
C++ as a language doesn't, but if you follow the convention that
C++ establishes in its libraries (where copy assignment & copy
construction == deep copy), it always works out correctly.
D doesn't have that convention so that's why we're running into
trouble.
