But how can I achieve the same result if S1 is a template

Also why neither "opCast"

There is a way to implicitly convert non-template user type, for
example:
struct S2
{
@property S1 s1() { return S1(); }
alias s1 this;
}
struct S1 {}
S1 f() { return S2(); } // implicit conversion from S2 to S1
But how can I achieve the same
