Comment (by facundo.dominguez):

 Currently all static names in a statically linked module are inserted in
 the SPT before the program starts executing main. When the module is
 loaded dynamically, the static names are inserted at load time.

 Making {{{unsafeLookupStaticPtr}}} pure will require changing the
 implementation so linking modules dynamically do not modify the SPT. It
 will also require doing something so the table is available when the
 function is used in (code loaded in) GHCi, unless nobody cares of breaking
 that.
