  You are correct for the case of a declared static constant in the
  declarative part of a subprogram.  I am referring to the deferred
  constant one sometimes exports from the public part of a package,
  rather than one declared locally to a subprogram.

  Of course the function would be in-lined, but that does not solve the
  issu you are citing. I agree that statically declared constants can
  be more efficient.
