His comments on array slicing are interesting.

Seems to me the solution should be to have *all* dynamic arrays be ArraySegment 
as all dynamic arrays under DMD are a slices of the full memory space.

Whatever happened to T[new]. Seems The Gods prefer having something like 
an "array builder" struct, and leave slices unchanged. Or maybe they'll 
remove the ability to increase the length of a slice.

Don't you see that what you say is negative? What you say lowers the mood of
people, makes them nervous. What you say is worse than useless, has a net
negative value.
So I suggest you to change and try to build something, to add value instead of
trying to remove value from the group of people and their work. Otherwise it
may be better for you to find other ways to use your time.

I read it as a positive comment. T[new] is cool, but it adds complexity 
to the type system and breaks backwards compatibility, so perhaps 
grauzone was saying he prefers one of those solutions?

Using ArraySegment's under the hood is kind of is what I am doing now; one 
interesting edge case is when you want to call functions written in other 
.NET languages (one main idea behind this project is to allow 
interoperability between D and other languages, and leverage existing 
frameworks rather than reinvent the wheel).

If you pass a slice to a "foreign" function that mutates elements in the 
array, it will not work as expected, because non-D code has no knowledge of 
slices.

The work-around is to construct a temporary array out of the slice, but any 
changes that the called function makes to that temp array will be lost.
This can be remedied by having the compiler generate post-call code that 
commits the changes back into the original array. It may work but is not 
efficient.

Currently I content myself with just issuing a compiler warning / error when 
such a situation is detected.

Cheers,
Cristian

I've been looking at that blog on and off a few times but I have missed a  
few posts. Has there ever been a beta?

There is still a long way before we can release a beta, but if you're 
curious you are welcome to take a look:
svn://216.154.214.180:8080/d.net/trunk/dnet

I am thinking about moving the project off my private server to CodePlex one 
of these days...

Cheers,
