Attempting to apply the bitwise operators to BigInt values results
compile time error.
Steps to reproduce:
void main()
{
import std.bigint;
import std.stdio;
auto x = BigInt(2), m = BigInt(11);
auto x1 = x & m;
auto x2 = x | m;
auto x3 = x ^ m;
writeln("x1 = ", x1, " x2 = ", x2, " x3 = ", x3);
x = BigInt(5), m = BigInt(27);
x1 = x & m;
x2 = x | m;
x3 = x ^ m;
writeln("x1 = ", x1, " x2 = ", x2, " x3 = ", x3);
x = BigInt(2), m = BigInt(18);
x1 = x & m;
x2 = x | m;
x3 = x ^ m;
writeln("x1 = ", x1, " x2 = ", x2, " x3 = ", x3);
}
Actual results:

bw.d(21): Error: 'x' is not of integral type, it is a BigInt
bw.d(21): Error: 'm' is not of integral type, it is a BigInt
Expected results:
x1 = 2 x2 = 11 x3 = 9
x1 = 1 x2 = 31 x3 = 30
x1 = 2 x2 = 18 x3 = 16
