But that actually makes it more similar to Python.

In Python, `for value in iterator: x(value)` is syntactic sugar for (roughly)

  while True:
    try:
      value = next(iterator)
    except IterationError:
      break
    x(value)

Basically, it seems that `while conditional` are both low-level control flow constructs in both: how do they differ between languages?
