parseJSON() from std.json doesn't work with CTFE.
But I can build objects with with my code that works over
std.json.
So if you convert (with mixins)
{
This code:
import std.stdio;
int very_very_long_function(in int k)
{
if (!__ctfe) writeln("Can't use ctfe!");
return k/2;
}
void main()
{
enum first = very_very_long_function(10);
writeln("First is ", first);
auto second = very_very_long_function(12);

Yes, or static local variables are ctfe initialized too.

CTFE only happens when it *has* to - when you write code that
specifically asks for or requires it.

Why second init doesn't work with CTFE?

template forceCTFE(alias expr) {
alias forceCTFE = expr;
}

There's no way to force it?
Just make a mutable copy of it, I think.
