What's wrong with

  auto c= a .* b;

except, that it is neither suggested nor supported?


Or

  auto c= a (*) b;

which was suggested some long time ago, but has not got through?


Is it horrible then to define:

void opDotMul(T)(out T c, T x, T y){
    assert( x.length ==  y.length);
    c.length= x.length;
    foreach( i,v; x){ 
        c[i]= x[i] * y[i];	  
    }
}
