Fails with:

[mono] ~/Desktop @ gmcs test.cs 
test.cs(22,28): error CS1502: The best overloaded method match for
`Test.Foo(System.Action<System.Collections.IList>)' has some invalid arguments
test.cs(5,29): (Location of the symbol related to previous error)
test.cs(22,28): error CS1503: Argument 1: Cannot convert type `lambda
expression' to `System.Action<System.Collections.IList>'
test.cs(24,17): error CS1579: foreach statement cannot operate on variables of
type `object' because it does not contain a definition for `GetEnumerator' or
is not accessible

That should compile and print to stdout all arguments passed to the executable.
