--- Comment #5 from Atila Neves <atila.neves at gmail.com> ---
A dummy postblit wouldn't work - it wouldn't actually fix up the value.
Duplicating the functionality of the C++ copy constructor is undesireable, and
using the copy constructor with the latest release candidate of dmd 2.086.0
doesn't work either.
