Is there a way to have warnings for shadowing values in F# in Visual Studio?

Question

To me shadowing of existing values like described in:

Shadowing and Nested function
immutable in F#
f# duplicate definition
FSharp for fun and profit com

Answer 1

One place I use shadowing is when resolving an optional parameter to a default value if no value was supplied.

member x.Foo(?myFlag: bool) =
    let myFlag = defaultArg myFlag false
    ...

Also F# Interactive, the way it's implemented now, would be pretty much completely non-functional if we didn't have shadowing.
