cfn arg with pointer to custom types throws exception about coffi HOT 2 CLOSED

I'll work on fixing this, it's highly likely it's just a bug in one of my inline function definitions. Your definitions as written here should work without change once I introduce a fix.

As for the readme, what this means here is that the value being passed will be allocated, serialized into, the pointer passed to the native function, but once the function returns as you have no access to that pointer you would be unable to deserialize the value stored in that argument pointer, as might be required for a function that modifies its arguments (e.g. an out parameter).
