C1 compiler
I'm Marcel Garus (he/him), a student at the 
In the open-source world, I work mostly on low-level things such as Rust, Assembly, or Zig. I love inventing new programming languages such as Candy, Martinaise, Soil, Mehl, Dungbeetle. Sometimes, I write articles on my blog.

One might initialize an array like this:
int a[/*hey*/] = { 1, 2 };The compiler currently does not support this.
It would be nice to be able to configure custom step sizes.
For example, one might want to access array elements like this:
int a[] = { 1, 2, 3 };
printf("%d %d %d", a[2.1], a[2.2], a[2.3]);
// Expected output: 1 2 3I tried compiling the test.c1 program from the repository and c1c crashed with the following backtrace:
