import std.traits: isMutable;
struct S {
immutable int i = 3;

pragma(msg, isMutable!S);
void main() {
S s;
s = S();
}
And is there a trait that takes the transitivity of immutability
in to account?

Both of these seem to work (as you pointed out)
// immutable(W!int)
auto si = wrap!(int)(cast(immutable)3); // or
wrap(cast(immutable)3);
// W!(immutable(int))

Without much confidence on my side, first, I think you need to make
the constructor parameter inout(T) as well. Otherwise, you may be
making a const(W!T) initialized with a non-const T.

Ok, thanks to Simen from another post [0], I just figured out what the
correct constructor and factory method for a template wrapper should be:
https://run.dlang.io/is/S4vHzL
struct W(T) {
T val;
this(U : T, this This)(auto ref U val) {
this.

isMutable only takes the type into account, it doesn't look to see if
all the internals are mutable.
It literally is this:

Hi,
I'm playing around with an Optional wrapper type. It stores a type T and
a bool that defines whether a value is defined or not:
struct Optional(T) {
T value;
bool defined = false;
this(U : T)(auto ref inout(U) value) inout {
this.value = valu
