Clasp uses an interesting CRTP pattern to insert statically (i.e. compile-time)
generated numeric IDs into global fields. However, these templates are
instantiated once per shared library---thus, whenever a library is linked, new
IDs are generated, and the original intent (safely type-casting objects across
libraries) is lost. To help the linker out, we make sure that these IDs are
only instantiated in clasp and not when building other libraries.
