in phobos toString only play with char*
remember char* is different from char[]
i use enki to parse a char[] buf, and set the substrings in buf to be the AA's keys and values, then i tostring AA["Key1"] , i can see not only the AA["key1"] given , but also something in buf all tostringed
a simple case couldn't be provided by now, but i think std.string should include a new func
char[] toString(char[] s)
{
return s;
}

The problem is actually the compiler can implicitly cast char[] to char*
then the toString take char[] in without any warnings or error message shown.
but it is dangerous to pass char[] to toString
maybe we don't neet the implicitly cast from char[] to char*
or we need to provide either of the funcs as the following:
char[] toString(char[]s)
{
static assert(`Error use of toString, u can't toString a String`);
}
or
char[] toString(char[]s)
{
return
}
