Here is GPT-J-6B output for comparison(I assume ChatGPT using 
their biggest model that has 176 Billion params compared to just 
6 Billions in this case), I had to adapt it and run several 
times, also had to use limit because I was running it on CPU.

One of the variants was simply using split directly in just one 
line. Another example had included console output but was quirky.

Sometimes I see how it tries using STL but with D syntax.

Anyway, haven't played that much with GPT-J, but it takes some 
trial and error to get something meaningful esp. with smaller GPT 
variants.
And running this on the CPU is no fun.

```
0: // A Dlang program that splits a string at each comma without 
using the garbage collector

import std.algorithm;
import std.stdio;

void main()
{
   string s = "Hello, World";
/// ---- (this part below is generated output) ----
   foreach (i; 0.. s.length)
   {
     if (s[i] == ',')
     {
       writefln("split string at comma '%s' in line %s", 
s.substring(0, i), s.length);
       writefln("into: %s", s.substring(0, i));
       split(s.substring(i+1).split(','));
     }
   }
}
```
