Adding two numbers has never been this awful
Normally, you'd add two numbers with the '+' operator. But why do that when you can use Type Extensions, custom operations on Computation Expressions, customer operators, and more?

Joint Life Annuity
This Joint Life Annuity calculation relies on the objects and functions defined in Single Life Annuity. A joint life annuity calculates the present value of an annuity from current age to death of a member and another life (spouse). The implementation below uses the AgeVectorBuilder from the Single Life Annuity snippet in two examples: The first defines a simple Joint Life Annuity that assumes no age difference between the two lives. The second assumes an N year age difference. The samples both rely on a male mortality table (PMA92 (C=2003)) and a female mortality table (PFA92 (C=2003)) which are extracts of publicly available mortality tables (http://www.actuaries.org.uk/research-and-resources/documents/pma92-pensioners-males-amounts).

Await Computation Expression (Task + Async Interoperability)
When writing asynchronous code in F#, one often needs to call methods in the .NET BCL that return Task or Task
5 people like thisrather than the F# native Async<'a> type. While the Async.AwaitTask function can convert a Task into an Async<'a>, there is some cognitive overhead in having to keep track of which functions return Task and which functions are Async. To simplify this interoperability, this code provides new `await` computation expression that supports using both Async<'a> and Task or Task inside it. This works by unifying the Task and Async types in the Awaitable DU, and overloading the Bind, ReturnFrom, Combine, and Using methods on the AwaitableBuilder Computation Builder to handle Awaitable<'a>, Async<'a>, Task, and Task .

Capture the rest of sequence on error
Computation expression that automatically captures the rest of the sequence that you are iterating over using a "for" loop so that the exception handler can do something clever with it.
