This program shows a dis-uniformity that maybe should be removed:


void main() {
void main() {
    uint[] a;
    a ~= 0;            // OK.
    a ~= [0];          // OK.
    a ~= [-1];         // OK(?)
    auto b1 = a ~ 0;   // OK.
    auto b2 = a ~ [0]; // Error.
}



DMD 2.063beta5 gives:

test.d(7): Error: incompatible types for ((a) ~ ([0])): 'uint[]' and 'int[]'
