Did you use that double curly bracket in `static foreach` so that you
don't get error for declaring stuff inside `static foreach` ?
Yes. 'static foreach' does not introduce scope, which can be pretty
useful. For example, one can define functions at module scope.
The subtle differences between 'static foreach' and '(compile-time)
foreach' can be surprising. For example, I don't understand why I can't use
foreach (i; 0 .. members.length) {
enum ident = __traits(identifier, members[i]);
// ...
}
Error: variable `i` cannot be read at compile time.
I think it should be. :) members.length is compile-time; so, 'i' should
be compile time.
And then, why can't 'static foreach' iterate over 'members'?
static foreach (member; members) {{
// ...
}}
Error: value of `this` is not known at compile time
Hm? Well, I am happy that there is always a path through. :)
