Agreed. Introducing *rvalue reference* requires such changes for

Indeed. It's incredibly inconsistent for struct literals to be lvalues.
Literals should always be rvalues. Allowing references to them with something
like const& like in C++ is of value, but that's of value with _all_
temporaries. struct literals should not be treated specially from other
literals or temporaries. Having
void func(ref S s) {}
S foo() {}
func(S(1)); //succeeds
func(foo()); //fails
is atrocious. It's incredibly inconsistent and confusing. S(1) should treated
identically as the return value of foo().
These will both work under my proposal.
