Testcase:

using System.Collections.Generic;

public class Expression {
    public static void Block(params Expression[] expressions) {}
    public static void Block(IEnumerable<ParameterExpression> variables, params
Expression[] expressions) {}
}

public class ParameterExpression : Expression {}

public class Test {
    public static void Main() {
        Expression e = new Expression();
        Expression.Block(
            new ParameterExpression[] {},
            e
        );
    }
}

Result:

Test.cs(13,20): error CS0121: The call is ambiguous between the following
methods or properties: `Expression.Block(params Expression[])' and
`Expression.Block(System.Collections.Generic.IEnumerable<ParameterExpression>,
