Ok, I fixed it. I just need to put (K) type parameter to the other opIndexAssign
D not allow overload operators/methods with different type parameters.
They must share same type parameters :
void opIndexAssign(K)(K c, size_t row, size_t cl) {... }
void opIndexAssign(K) (K v, size_t j) { ... }
Finally I try this small test code :
struct A(T, int U) {
T x;
static enum foo = U;
Tout opCast( Tout ) ()
if (isA!Tout) {
Tout nt;
nt.x = x;
return nt;
}
string toString() {

Well, the problem is that I must do the cast always, see :

auto tcol = Mat4r.IDENTITY;

Thanks. I imagined something similar, that "Vector" alone not is type.
How I can templatize opIndexAssign function ? I tried this :
void opIndexAssign(U)(U v, size_t j) {
col[j] = v;
}
And I get a error :
Error: template zmath.matrix.Matrix!(float,2).Matrix.opIndexAssign(U) conflicts
with fun

auto tcol = Mat4r.IDENTITY;
auto v = cast(tcol.VCol) Vec3f(1, 2 ,3 );
auto v2 = Vec4r

I have a parametrized struct (Vector!(T, dim)) that takes two parameters
(Type and a number). And made some Alias with defaults parameters.
In other struct (Matrix!(T, dim)), that uses these struct to represent a
matrix in column-major order. I have a internall alias for Vector using
internally
