Comment (by facundo.dominguez):

 When we moved {{{inline-java}}} to use a ghc plugin, we stopped using the
 static pointer table. But it would have broken because of this.

 {{{inline-java}}} was using the static pointer table to store java
 bytecode. At runtime, the SPT was traversed looking for the bytecode to
 pass it to the JVM. The bytecode was inserted in the SPT by creating some
 static forms which were never accessed other than through the SPT
 traversal.

 But as I said, inline-java doesn't use the SPT anymore. Maybe mnislaih has
 another use case.

 The documentation for {{{staticPtrKeys}}} is available in the module
 {{{GHC.StaticPtr}}}.
 https://www.stackage.org/haddock/lts-9.0/base-4.9.1.0/GHC-StaticPtr.html

 We could say more in the user guide, of course.
