If you're looking to use aliases to functions for a functional style of programming, what you're looking for is the delegate keyword. You can think of delegate as making an interface, except it's for a function.

so instead of using Expression = Func; using Converter = Func, Expression>; you do delegate string Expression(); delegate Expression Converter(List tokenizedExpressions);
