> In the code above, make([]proc(msg: string), len(arr)+1) generates a slice of procedure pointers with a length of len(arr)+1. Essentially, it allocates memory on the heap and returns a slice header, which includes a pointer to the allocated memory, along with the length and capacity of the slice. I guess things get exciting when that allocation fails, given that such a failure is nowhere checked for and the possibility of such failure is nowhere mentioned.

Odin supports multiple returns and the `make` proc returns an error value that can be optionally checked.

  Optional error checking based on a second return value is just asking for footgunnery, Go made this same (IMO) mistake.

    One can use `@(require_results)` to force the user to check for error. That paired with `or_return` or `or_else` in Odin mostly take away all foot guns.
