This is one of the things that the upscope() your patches removed from
createparam() was checking for:  a special hidden by a local.  (Might
nevertheless have had some of the edge cases wrong.)  If loading
happens (or if the named reference declaration is omitted), you should
see this:

(anon):2: read-only variable: SRANDOM

because the default for locals with the same name as specials is to
retain the special behavior.  This is currently broken with your
patches applied, including the explicit case:

   local +h SRANDOM

This is avoided by

  local -h SRANDOM

in which event your analysis about named reference dereferencing does apply.
