The journals take a mix of articles written for the journal and blog posts adapted for the journal. So yes.

I forgot about using enum instead. I think I've only briefly encountered it before. I'm aware of the global storage of static in this context. I like that it's the same keyword for static foreach; that's kind of what I was thinking when I wrote that just adding a static can result in compile-time execution. BTW, that tour page needs updating, it has a few errors in it. You mean the Dlang tour? I've been meaning for a while to be able to generate a url to its Gems section but I've never managed to untangle its Vibe.d structure enough to do so.

Yeah, it's mostly the C that I wanted to get rid of. I do wish the static foreach had worked, though! It's odd that you can't have compile-time associative arrays.

What triggers the compile-time execution is the fact that static
*initializers* need to be decided at compile time.
So while it is executing the regex building at compile time in your
example, there are other ways to do it, and in this case, I'd prefer
using an enum. You can also use ctRegex.
The drawback of using static is that it keeps its value between function
calls:
int bar() { return 42; }
void foo()
{
static x = bar();
x += 5;
writeln(x);
}
void main()
{
foo(); // 47
foo(); // 52
}
So it may not be what you are looking for.
Whereas if you use:
void foo()
{
enum x = bar();
writeln(x + 5);
}
it will always write the same answer (and not allocate global space for it).
BTW, that tour page needs updating, it has a few errors in it.
