The snag about this announcement is that it does NOT actually explain how this might be used in a script, it also seems to contradict itself:Wait Enabled
This is a big deal in itself.
You may think of “wait” as just one command in your code, but that isn’t the case. In reality, the LiveCode engine uses “wait” internally for a number of operations. Because “wait” will now work, you can use blocking operations in your Web app such as get, post and delete url. A significant set of operations and features can now be implemented for your app without awkward workarounds.
"You may think of “wait” as just one command in your code" seems to imply one might already be able to include 'wait' in one's code.
But, "Because “wait” will now work" states that pre-version 10 'wait' has not worked.
I, for one, would be very grateful if someone could explain all of this, because if it "is a big deal in itself" then it deserves
a proper and full explanation.
