I'm at #hopl and here is a potted history of the addition of what I call "computational modalities" to C# and F# - these include addition of new syntactic forms like comprehensions, or "modal" reinterpretation of existing syntactic forms.
First, in 2000-02, Todd Proebsting of MSR initiated an effort to convince the C# design team to add iterator methods, based on his experience with the Icon language, of SNOBOL fame. Iterator methods serve as a form of computed collection. 
In 2005-07, those of us in F# looked at iterator methods and past history of tasksm promises, monadic and comprehension syntax to form F# async, F# sequences, F# list comprehensions and the general F# computation expressions.
