Anything LiveCode Can Learn From GO

I wasn't thinking about high language per se.   but more from an engine point of view, specifically use of "Goroutines"

"But, most of the modern programming languages(like Java, Python etc.) are from the ’90s single threaded environment. Most of those programming languages supports multi-threading. But the real problem comes with concurrent execution, threading-locking, race conditions and deadlocks. Those things make it hard to create a multi-threading application on those languages.
{snip]
On the other hand, Go was released in 2009 when multi-core processors were already available. That’s why Go is built with keeping concurrency in mind. Go has goroutines instead of threads. They consume almost 2KB memory from the heap. So, you can spin millions of goroutines at any time.

How Goroutines work? Reffrance: http://golangtutorials.blogspot.in/2011/06/goroutines.html

Other benefits are :

    Goroutines have growable segmented stacks. That means they will use more memory only when needed.
    Goroutines have a faster startup time than threads.
    Goroutines come with built-in primitives to communicate safely between themselves (channels).
    Goroutines allow you to avoid having to resort to mutex locking when sharing data structures.
    Also, goroutines and OS threads do not have 1:1 mapping. A single goroutine can run on multiple threads. Goroutines are multiplexed into small number of OS threads.
=========

And from the reference a "Goroutine" may be not language specific and maybe (I don't know much about the engine) I am dreaming about the rabbit in the moon, but, for Mark's "idea machine" there is this:

" Effectively for us goroutines hides many of the internal machine complexities in achieving parallelism. This also means that the language designers could implement changes to how goroutines scale on the machine taking advantage of hardware and CPU improvements."

    The 2 can make a great couple indeed.  But neither can replace the other.
