Thanks a lot for the all the comments and instructions shown here. Perhaps writing a mixin at module where the main method is located will do that exactly. others may be dll and could be unloaded and cause __dtor to be called. Will try such direction. Thanks people. -- Matthew Ong email: on...@yahoo.com

I should clarify that when I wrote this, I thought the description was from the module.html file, not the class.html file. Ali pointed out the bug in the web site. So I didn't get why you were talking about classes, sorry :) Class and module static ctor/dtors should be exactly what you are looking for. -Steve

It is more like an entire application shutdown event. So I will be placing that at the same module dtor and file as the main(string[] args) using template mixin. That might work. I will test that out. -- Matthew Ong email: on...@yahoo.com

(filed as http://d.puremagic.com/issues/show_bug.cgi?id=6055 ) Note that class static dtors are exactly the same as module static dtors, they just are inside the class namespace. -Steve
