The point is that I was trying to avoid some cycle between modules, detected by 2.072. This bug leads to pollution in the use of static this only to workaround the limitation...

Wasn't someone working on a Associative Array static type that could be created at CTFE and run at runtime?

I'm guessing there isn't.
Sadly still running into issues because of this :(

Actually I did a DMD patch for that some time ago.

It's here: https://github.com/dlang/dmd/pull/13087

If there is interest in this I might revive it.

I feel like this should be done, if only for the sake of consistency

We can add an idiom about how initializing large AAs can lead to binary bloat, so use the shared static this(){} workaround instead

Would you please revise it? I'll take your side on this.

The reason why it needs to be shared is because it's only executed once, where as just static this is executed for each thread.
