digitalmars.D - DTL?

I saw mention of DTL in the Andrei/Walter slides.
But it didn't mention who is doing it, where to find it, or if it's not 
available yet, when approximately it would debut.

Also, will it be phobos dependent?

Any info?

DTL is a now defunct library that was originally developed by Matthew 
Wilson.  Its main selling point was an intriguing interpretation of 
ranges combined with the usual STL-like containers.  I gather that such 
a library is on Walter and Andrei's "to do" list, and it's on mine as

There is no reason that such a library would need to depend on either 
Phobos or Tango, aside from its possible inclusion in either or both.

Yeh, I remember that DTL.  However that's defunct as you say and the 
"Standard Library" section from the Andrei/Walter presentation contains 
just one slide and it's titled "DTL" so I took it that they were 
co-opting the name and starting afresh.

I agree that it would be possible to make it independent of runtime, but 
it's also easy to think of small things that might thwart that.  Like
1) toString
2) different std library exception hierarchies
3) use of low level library functionality like std.string.format.

Those are good points, but I'm not sure that the containers will 
natively provide an interesting toString() or need to use something like 
std.string.format (but I'd be interested to here places where you think 
that is necessary).  The exception hierarchy is an interesting point, 
but it's possible that DTL will get its own hierarchy, for better or 
worse.  Andrei has indeed done some work on it, but he has lots of 
things to keep him busy, as you can imagine.

Same here, though inspired by the original I assume.  I think ranges 
were mentioned at the conference when that slide came up.

True enough.
