Strange return value with "_context"

[cuiliang]

https://dotnetfiddle.net/6IEtGc

code:

// @nuget: Z.Expressions.Eval

using System;
using Z.Expressions;
using System.Collections.Generic;

public class Program
{
    public static void Main()
    {
        // From simple expression...

        var dict = new Dictionary<string, object>();
        dict.Add("_context", "aaa");
        // To complex code.
        var result = Eval.Execute("\"_context\"", dict);

        Console.WriteLine(result);      

    }
}

returns zzz_f900d830_3564_44fc_a449_570a57c64ff5 which should return a string _context .

remove _ from variable name will return correct result.

Hello @cuiliang ,

Unfortunately, we still have not succeeded to fix this issue correctly without getting some side impact as we know some people use that feature in their code (Dict key is replaced by value).

However, we choose to add an option to disable this behavior as we understand not everyone wants it and as you show, it cause also some impact.

You can disable it with the options DisableAutoReplaceDictionaryKey = true.

We will not close this issue as we might want to try it again but for now, using that new option will be the solution for this behavior.
