Summary: Wrong error message in a case of alias-this-array

This program shows a correct error message:
void main() {
int[5] a;
double i = 0;
a[i] = 0;
}
test.d(4): Error: cannot implicitly convert expression (i) of type double to
uint
While this code in a similar case shows a not good error message:
struct Foo {
int[] data = [0];
alias this = data;
}
void main() {
Foo a;
int i1 = 0;
a[i1] = 10; // OK.
assert(a.data[0] == 10);
double i2 = 0;
a[i2] = 20; // Error.
}
DMD 2.061alpha gives:
test.d(11): Error: no [] operator overload for type Foo
