           Summary: array[]++ and array[]-- too?
           Product: D

          Severity: enhancement
          Priority: P2

This code contains two operations that are refused by DMD2.055beta:

void main() {
    int[10] a;
    a[] += 1; // OK
    ++a[];    // OK
    --a[];    // OK
    a[]++;    // line 6, error
    a[]--;    // line 7, error
}


test2.d(6): Error: slice expression a[] is not a modifiable lvalue
test2.d(6): Error: 'a[]' is not a scalar, it is a int[]
test2.d(6): Error: cannot cast int to int[]
test2.d(7): Error: slice expression a[] is not a modifiable lvalue
test2.d(7): Error: 'a[]' is not a scalar, it is a int[]
test2.d(7): Error: cannot cast int to int[]


Maybe it's better to allow the last two lines too.
