I think it is a bug:
import std.stdio, std.random;
struct Mystruct {
//mixin(`auto id = uniform(0, 10);`);
// Error: static variable initialized cannot be read at compile
time
int val;
}
void main() {
Mystruct test;
test.val = uniform(0, 10); // OK
writeln(test.val);
mixin(`auto n = uniform(0, 10);`); // OK
}
