To manage BigInt arrays in a handy way (and in a way uniform with arrays of integers), I'd like this code to work:


import std.bigint;
void main() {
    BigInt[5] arr;
    arr[] = 1;       // line 4
    arr[1 .. 3] = 2; // line 5
}


But with dmd 2.057beta it gives:

test.d(4): Error: cannot implicitly convert expression (1) of type int to
BigInt[]
test.d(5): Error: cannot implicitly convert expression (2) of type int to
BigInt[]

This doesn't have anything to do with BigInt. Rather, it's a request for implicit conversion to apply to array block assignment.

Reduced example:

struct S
{
   void opAssign(int n) {}
}

void main()
{
   S[20] s;
   s[] = 6;
}

bug.d(9): Error: cannot implicitly convert expression (6) of type int to S[]

It seems reasonable enough. It could be problematic if the thing being assigned is an array, eg

void opAssign(int[] n) {}

but we have that problem already with block assignment to arrays of dynamic arrays.

AFAIK array block assignment isn't mentioned in the spec at all.
