--- Comment #3 from Jonathan M Davis <issues.dlang at jmdavisProg.com> ---
As much as this sucks, it really isn't a bug. const and postblits are 
incompatible by their very nature, because the postblit copies and then
mutates, which violates const. So, arguably, going with postblit constructors
over copy constructors was a mistake. There's a DIP that tries to fix the
problem ( http://wiki.dlang.org/DIP49 ), but it was deemed to be way too
complicated. This is a design problem in the language that needs to be fixed
(possibly by adding copy constructors) and not a bug in the compiler. It is
expected behavior at this point.
