You should just take Init, without the in.
"in" means that you won't modify AND that you won't let any
reference to the argument escape the function's scope. The
second part isn't enforced by the compiler right now, but this
may change at some point.
"in" basically is "look, don't keep", and since ctor arguments
are often kept in the class, it isn't ideal there.
But plain non-const, non-in structs should be fine, that works
the same way as a regular function argument list.
Thanks but won't the struct be copied at every function call then
?
