        OS/Version: Windows
            Status: NEW

          Severity: normal

I don't understand this bug. D2 code:


void main() {
    enum uint N = 4u;
    char[] A = "hello".dup;
    uint[immutable char[N]] dict;
    dict[*cast(immutable char[4]*)(A[0 .. N].ptr)] = 0; // OK
    dict[*cast(immutable char[N]*)(A[0 .. N].ptr)] = 0; // line 6, error
}


DMD 2.059head gives:

test.d(6): Error: cannot implicitly convert expression
(*cast(immutable(char[N]*))cast(char*)A[0u..4u]) of type immutable(char[N]) to
immutable(char[4u])
