Hi,

I just run into this problem again:

https://stackoverflow.com/questions/26861708/what-is-the-syntax-for-declaring-a-constant-stringchar-aa

So, the solution still is to use:
```
static this () {
   ...
}
```

What happened to this comments:
"""

Still not there yet, after ~10 years?

Yep.

I have a library solution: https://code.dlang.org/packages/newaa

You can declare a `Hash!(char, string)` in module space, and then use it 
as an AA later.

However, it needs to not be const. The Hash type does not set itself up 
as an AA doppelganger until you call `asAA` on it, which means it needs 
to set up some internal things, and therefore needs to be mutable. I 
think I can make a method that does this, so you can use `const 
Hash!(char, string) = [ ... ]`, but it still can't change the type to an 
actual AA (the compiler won't let that work).

Wow, over a year since I did anything on it. Probably should tinker a 
bit more.
