Restore unification in PP, e.g. with a Palindrome.pp grammar:

    %skip  s \s
    %token q \w

    #rule:
        ( <q[0]> rule()? ::q[0]:: )*

and in a shell:

    $ echo roma summus amor | hoa pp Palindrome.pp 0 -v dump
    // AST.

Other examples: XML tag, quotes etc.
Note: a unification is local to a rule instance.
Have fun with it :-).
