Re: Associative Array, key and value as type of string or char[]

It seems you are right. I get the same error. You should open a 
bug report for this.
But as long as it isn't fixed you can use an output via foreach.
import std.stdio;

void main() {
        string[string] ch_Description = [
                "kill" : "kills a process",
                "pause" : "pauses a process"
        ];
        
        // writeln(ch_Description); // does not work, but it should
        foreach (string key, string value; ch_Description) {
                writeln(key, ':', value);
        }
}
