Some languages (e.g., Go, Swift, ...) support guards in loops.

This would be a nice addition for imperative-style constructions, as in:

foreach n in l {
  if n > 10 {
    println(n)
  }
}

This could be replaced by, say:

foreach n in l when n > 10 {
  println(n)
}

The syntax is to be discussed, this could be nice, too:

foreach n in l, n > 10 {
  println(n)
}
