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.val = val;
}
}
auto wrap(T)(auto ref T t) {
return W!T(t);
}
Seems to catch all cases!
And instantiate a new template for all mutabilities. Whereas inout would
only instantiate one (and disallows modification of val if not const or
immutable).
