Thanks for the pointer, it is pretty much exactly what the `Once` type
in Rust is.
It's not exactly what I'm thinking of in this case, but since it is
implemented with static key, maybe we can do something similar with a
static key? So switch the return value of the `ModuleParamAccess::read`
function depending on weather the module parameters have been written
and while they haven't just return a dummy value and WARN.
Thoughts @Andreas?
