i try to compile the following slightly modified sample from the

template declaration. Candidates are:

========================

what's wrong? if i replace OwnerTerminated with int or simply 
remove everything is ok.

if i replace with my own struct Terminate - fail.

any help would be appreciated.

This is a template function literal taking an argument named 
"OwnerTerminated", not a function with an unnamed parameter of 
type OwnerTerminated. Quite a sublime trap, admittedly.

In the future you might want to post similar questions to the 
digitalmars.D.learn group instead.

Hope this helps,
David
