I've found http://www.dsource.org/projects/tango/ticket/396 which indicates that bind functionality is indefinitely postponed.  It's even marked as a closed ticket!

I'm in the process of porting code over from phobos to tango.  All I have left to do is resolve all of my calls to bind.

I'm using delegates as generic signaling between threads.  The problem is that creating a delegate on the fly (using {}) won't work in many cases.  Because of the async nature, the local stack frame won't be available and all accesses to variables are lost.  It's a real hack to manually create helper objects (with a constructor and opCall function) for simple things that can be replaced with bind(&foo.bar, a, b)

Even if not part of tango, does anyone have any generic tango-based solution for this?  (Note that the phobos implementation of bind does not work completely in gdc 0.23.  I'm hesitant to just copy the phobos implementation)

The change was made around the time 0.99 was released, because no one had been asking about it.  And we weren't in full agreement about whether or not it was a necessary feature.  If you have a compelling use case, post it to the Tango forums and I suspect the decision will be reconsidered :-)

I actually have the revised version of bind that was slated for inclusion in Tango.  You can ask its author (h3r3tic) for a copy as well.

That's now done.
