Test case:


-----------------------------------
static assert( {
    immutable qq = "qq";
    string q = qq;   // <-- from immutable(char[]) to immutable(char)[]

    int[string] pieces = ["a":1];
    pieces[q] = 0;   // <-- can't interpret

    return true;
}() );
-----------------------------------
x.d(9): Error: cannot evaluate delegate pure nothrow bool()
{
immutable immutable(char[]) qq = "qq";
string q = qq;
int[string] pieces = ["a":1];
pieces[q] = 0;
return true;
}
() at compile time
x.d(1): Error: static assert  (delegate pure nothrow bool()
{
immutable immutable(char[]) qq = "qq";
string q = qq;
int[string] pieces = ["a":1];
pieces[q] = 0;
return true;
}
()) is not evaluatable at compile time
-----------------------------------
