--- Comment #2 from Basile-z <b2.temp at gmx.com> ---
There was a bug but it's fixed since 2.063,

the following code with "all compilers" on run.dlang.io confirms:

---
module no_bug_here;

import std.traits: moduleName;

struct S
{
    enum se = 8;
    static assert(moduleName!se == "no_bug_here");

    struct I
    {
        enum ise = 8;
        static assert(moduleName!ise == "no_bug_here");
    }
}

void main(string[] args)
{
    enum le = 8;
    static assert(moduleName!le == "no_bug_here");
}
