[D2] How to not full closure?

[Frank Benoit]

On Nov 27 2007 in this NG, there was this thread "How to not full closure?"
See:

For me, this is still a problem i see in using D2.
E.g. when i pass a delegate as a search criteria to a containers find 
function, the triggered heap allocation can destroy all of the 
performance. Even worse, i cannot manually delete the stack frame.
Imagine this function is called in a loop!

So this still is a D2 show stopper for me. Delegates are a very 
important D feature. Full closures remove delegates for performance 
critical code, without giving an alternative.

Please give this a high priority.
