Generators - Maintaining Local Frame State

The Python literature mostly discusses generators in the context of iterators. This masks the subtle truth:

  • Generators are objects which maintain the local frame
    • These are not coroutines as there is no true stack frame maintained
    • But, you can invoke other generators from a generator getting you closer to where you might want to get
    • Python Extensions such as “Greenlets” support true coroutines

  • Twisted supports callbacks to “yield” using the “send” operator through the “inlineCallback” mechanism

    • Twisted folks view this as syntatic sugar. That Tarbox guy thinks they're a bigger deal
