**Skip keyword** (drop items from results):

```mlld
var @filtered = for @x in @items => when [
  @x.valid => @x
  none => skip      >> omit this item from results
]

>> Equivalent to inline filter, but allows complex logic
var @processed = for @item in @data => when first [
  @item.type == "a" => @transformA(@item)
  @item.type == "b" => @transformB(@item)
  * => skip         >> unknown types dropped
]
```
