error occur when using "dynamic" and "enum"

[sericaer]

When I used the "dynamic" and "enum" as follow:
class DynamicEnum
{
enum TEST
{
t1
}

    TEST _test;

    void Selected(dynamic param)
    {
        _test = param;
    }
}

I got an error without useful info:
error : 10(18,14): native.DynamicEnum.Selected(dynamic)
UnityEngine.Debug:Log(Object)
CSharpCompiler.UnityLogTextWriter:Log(String) (at Assets/ThridParty/mcs_ICodeCompiler/UnityLogTextWriter.cs:19)
CSharpCompiler.SourceCodeBundle:.ctor(ScriptBundleLoader, IEnumerable1) (at Assets/ThridParty/mcs_ICodeCompiler/ScriptBundleLoader.cs:227) CSharpCompiler.ScriptBundleLoader:LoadAndWatchSourceBundle(IEnumerable1) (at Assets/ThridParty/mcs_ICodeCompiler/ScriptBundleLoader.cs:41)

But if change the type of _test as "string", the error is disappeared

Does your code work anywhere else ?
How about Enum.Parse, usually you can not cast enum's directly, not in C# at least,
