Comment (by mboes):

 > That failing, the simplest solution could be to document that the module
 defining static pointers needs to be imported transitively into the main
 module of an executable supposed to find them.

 That solution would be as anti-modular as non StaticPtr remote tables.
 Losing modularity would defeat much of the purpose of this language
 extension.

 Surely we can let the linker know that downstream modules *might* depend
 on `ALib.Things`?
