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.
