    Remove 'postderef' argument to PPIx::Regexp->new().  Postfix
    dereference is always recognized.

0.084           2022-04-02      T. R. Wyant
    Require PPI 1.238 for postfix deref support, and recode the
    postfix deref logic in terms of 1.238's functionality.

    Parse '@{[ ... ]}' as code, not interpolation.  This is more in line
    with what it actually represents, and allows correct versioning of
    postfix dereferences.  But is is an incompatible change.
