From @zoffixznet

Originally found this in behaviour of Z meta operator​:

  <Zoffix__> m​: dd <a b c>.any Z <d e f>.any
  <camelia> rakudo-moar 10f840​: OUTPUT​: «((Mu, Mu),).Seq␤»

Which works fine with X metaoperator​:

  <Zoffix__> m​: dd <a b c>.any X <d e f>.any
  <camelia> rakudo-moar 10f840​: OUTPUT​: «((any("a", "b", "c"), any("d", "e", "f")),).Seq␤»

I dug a bit and found the cause to be in Any.iterator​:

  <Zoffix__> m​: dd Seq.new​: any('x').iterator
  <camelia> rakudo-moar 10f840​: OUTPUT​: «(Mu,).Seq␤»

But after that I lost the trail and unsure where the bug is hiding...
