    undefine seen at:
      <unknown file>, line 1
    Will be removed with release v6.e!
    Please use another way: assign a Nil; for Arrays/Hashes, assign Empty or () instead.

Will that deprecation require a conditional and two assignments
for mixed data?

[$a, @a, $b, %c, $c, &d].map: { .&undefine};

[$a, @a, $b, %c, $c, &d].map(
    { $_ = $_ ~~ (Associative,Positional).any ?? Empty !! Nil });
