    $\begingroup$ Why not With[]? With[{p = 3}, HoldForm[p - 2]] $\endgroup$ – J. M.'s ennui Mar 15 '16 at 3:25
  • $\begingroup$ @J.M. Yes that is better. Why not add a separate answer? $\endgroup$ – Sean Mar 15 '16 at 3:31

    $\begingroup$ Because that bit is also in the thread you linked to, and the threads that thread is linked to. $\endgroup$ – J. M.'s ennui Mar 15 '16 at 3:33

Here's one way:

HoldForm[p - 2] /. HoldPattern[p] :> RuleCondition[p]

    $\begingroup$ Sean, perhaps you could add the With method outlined by J.M. in your answer, since you found it useful as well. (+1 for self-answering!) $\endgroup$ – MarcoB Mar 15 '16 at 3:43
