Description
a.hexpat
#pragma once
import std.io;
std::print("{}", "Import a");
b.hexpat
#pragma once
import a;
The following code will output Import a twice. I am expecting that module a should be executed only once as it is guarded with pragma once.
import a;
import * from b as B;
B b @ 0;

Research direction
Run the a.hexpat and b.hexpat reproducer, then trace how the direct import and import * from b as B path resolve #pragma once. Done means the sample prints Import a only once while preserving the aliased import behavior.
