`LVRET` detects if a sub is called as an lvalue (or something like that). I have no problem putting an SV on the stack, the problem is getting the following to compile `sub foo :lvalue { lvalue_xs_sub() }` [download] I could avoid it with something like `sub foo :lvalue { out_param_xs_sub(my $x); $x }` [download] but the point is to create a test for a bug I want to fix so I can fix another bug (delayed object destruction) in `substr`, `pos` and `vec`.
