How to evaluate a JSON file at compile time and create a struct out of it?

[holyzantaclara via Digitalmars-d-learn]

Hello hello everyone ^_^,

I am new in D, and started this morning. I found a way to read a 
file at compile time with `-J.` and `static string content = 
import("my_json_file.json")`

But then tried to statically evaluate with `static JSONValue j = 
parseJson(content)` but it fails.

```sh
main.d(12): Error: variable `content` cannot be read at compile 
time
main.d(12):        called from here: `readJSON(content)`
```

Is there a way to achieve this?

My goal is to have a JSONValue at runtime that would be already 
present in the binary. Cause the JSONValue is huge. Like 
megabytes of data... And no I don't want to deal with a database 
for now.

Thank you !
