    Remove 'postderef' argument to new().  Postfix dereference is always
    recognized.

    Recognize postfix deref in '@{[ ... ]}' for determining minimum Perl
    version.  This recognizes all forms of postfix dereference,
    including ->%*, ->&*, and ->**.  NOTE that for now this remains a
    PPIx::QuoteLike::Token::Interpolation.

    Require PPI 1.238 for postfix deref support, and prune code that
    dealt with PPI's old behavior.

    Postfix %*, &*, and ** do not interpolate.

    Correct perl_version_introduced() for interpolated postfix scalar
    deref.
