Description
Since F# 4.0 it has been possible to do C# LINQ style automatic convertion of function arguments into quoted expression trees. In the case of FSharp.AWS.DynamoDB this means that an update expression can be written as follows:
table.UpdateItem(key, fun e -> { e with Value = e.Value + 1L })
without having to quote the lambda argument. It's a nice enhancement without introducing any breaking changes.

Research direction
Start by reading the linked F# 4.0 auto-quotation design and locating the transaction or update-expression APIs that currently require quoted lambdas. Confirm how the existing UpdateItem argument is represented, then define done as accepting the unquoted lambda syntax shown without breaking existing callers.
