I stumbled into this problem with a struct having an immutable member.

Apparently, any kind of const-ness taints the struct, which prevents calling
the destructor. 

In my case, declaring the destructor const/immutable didn't help. :(
Apparently, you can't have struct with immutable members as an "in" parameter,
since that does the "const scope" thing, which triggers the destructor, which
causes the failure.


Also: the "const ~this()" syntax works, but "~this() const" does not, which
seems odd since it works for other method names.
