static foreach considered

[Andrei Alexandrescu via Digitalmars-d]

Walter and I are looking at ways to implement it. Here's a 
baseline without static foreach - a "trace" function that prints 
function calls before they are made:

If the function is overloaded, that won't work. In such cases, 
static foreach might be helpful. Here's code from the cycle "I 
have a dream":

I'm trying to collect together motivating examples and to figure 
out the semantics of the feature.
