## For loops
The `for` loop syntax is currently in transition, and will switch from the old
closure-based iteration protocol to iterator objects. For now, the `advance`
adaptor is required as a compatibility shim to use iterators with for loops.
The `foreach` keyword is transitional, and is going to replace the current
obsolete `for` loop.
