It is a good idea and I've bandied it around before, and it has its 
merits. One of its problems is it only works for cases where the 
delegate is the last parameter. Can't have arrays of delegates like the 
example in http://www.digitalmars.com/d/lazy-evaluation.html.

It also doesn't work where one wants the lazy evaluation function to 
return a value.
