+You can type your C<Pointer> with passing the type as parameter. It works with native type
+but also C<CArray> and C<CStruct> defined type. NativeCall will not implicitly alloc the memory for it
+even when calling new on them.
+It's mostly useful in the case of a C routine returning one or if emebeded in a C<CStruct>.
+
+You have to call C<.deref> on it to access the embeded type.
