Umm... Walter, this still isn't fixed.

Not trying to be a pain or anything, but in this post:
http://lists.puremagic.com/pipermail/digitalmars-d/2007-December/029769.html
I said: "I certainly hope you will look at the thread "Constancy lost
when compiling template mixin", and respond in some way - even if only
to tell me I've made some obvious and stupid error - because the issue
raised there is one that I /do/ need solving.", and then you said, and
I quote:

"I wouldn't worry about that right now, as the const stuff is getting
revised again."

OK, so I waited for the revision. Now we're at D2.009, and this bug
has not gone away. Please, please, please could you respond - either
to tell me I've done something stupidly wrong, or to assure me that it
is indeed a bug, which you plan to fix in D2.010 (for which I am now
waiting ... patiently...)

Thank you
