+ * \brief Property of runtime module
+ * We classify the property of runtime module into the following categories.
+ * - kBinarySerializable: we can serialize the module to the stream of bytes.
CUDA/OpenCL/JSON
+ * runtime are representative examples.
+ * - kRunnable: we can run the module directly. LLVM/CUDA/JSON runtime,
executors (e.g,
+ * virtual machine) runtimes are runnable. Non-runnable modules, such as
CSourceModule, requires a
+ * few extra steps (e.g,. compilation, link) to make it runnable.
+ * - kBinaryExportable: when the module is kBinarySerializable and kRunnable,
we consider this
+ * module as binary exportable. A binary exportable module can be integrated
into final runtime
+ * artifact by being serialized as data into the artifact, then deserialzied
at runtime. This class
+ * of modules must implement SaveToBinary, and have a matching deserializer
registered as
+ * 'runtime.module.loadbinary_<type_key>'.
+ * - kDSOExportable: we can export the module as DSO. A DSO exportable module
(e.g., a
+ * CSourceModuleNode of type_key 'c') can be incorporated into the final
runtime artifact (ie shared
+ * library) by compilation and/or linking using the external compiler (llvm,
nvcc, etc). DSO
+ * exportable modules must implement SaveToFile.
+ *
+ * Please note that kDSOExportable is a mutual exclusive property with
kBinaryExportable.

Review Comment:
Used `enum ModulePropertyMask : int` instead for implicit casting.
