There are two more corrections to make.
Both in sliceIt.
Note: array is a function not a type and is for ranges, slices are
built in language concept. Associate Arrays (map) use the syntax
``Type[Type]``.
While I do understand what you're saying, I'm not sure I understand how
to fix the code.
1. Changing function's argument type to `Array(string)` results in the
following error: `Error: function declaration without return type.`
2. Adding function type `Array(string) sliceIt(...)` results in the
following error: `Error: function declaration without return type.`
3. Finally, changing function's argument type to `string[]`, so function
definition looks like this:
```
auto extract_arg_names(string[] def_words_arr){...};
```
That is correct yes.
results in, what I presume, is a runtime error:

PS. Found more correction in the original code. The variable
`def_words_arr` should just be `words_arr`. Was not paying attention
when simplifying the code to post here.
Yes, that is the second one.
My version that runs:
```d
import std.stdio;
import std.regex;
import std.string;
import std.array;
auto sliceIt(string[] words_arr) {
int i = 1;
string word;
while(i < words_arr.length) {
word = words_arr[i];
if(matchFirst(word, r"^[A-Z]+$")) { break; }
i++;
}
return words_arr[1..i];
}
void main() {
auto words = ["HELLO", "world", "hi", "ENDOFTHERUNWAY"];
auto resulting_arr = sliceIt(words);
assert(resulting_arr == ["world", "hi"]);
}
```
