I have found out the following problem:

>>> require 'System.Core, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089'
=> true
>>> include System
=> Object
>>> include System::Linq::Expressions
>>> Expression.Call
:0: wrong number of arguments (2 for 4) (ArgumentError)
>>> Expression.Parameter
:0: undefined method `Parameter' for TypeGroup of Expression:Microsoft::Scripting::Actions::TypeGroup (NoMethodError)

Obviously the Call method was recognized but the Parameter one not. Should I file a bug or this is known and will be fixed?
