Enum type parameters with a default value fail to compile.

[synergiance]

Describe the bug in detail: When a method takes an enum type as a parameter, and also gives it a default value, UdonSharp's compiler seems to forget that it is the same enum type being passed in. (System.ArgumentException: Type provided must be an Enum.)

Provide steps/code to reproduce the bug: Declare an enum:

public enum MyEnum {
    MyFirstValue, MySecondValue
}

Declare a method with that enum type as a parameter and uses a default value:

public void MyMethod(MyEnum myEnumParameter = MyEnum.MyFirstValue) {
    // Method content
}

Call that method:

MyMethod(MyEnum.MySecondValue);

Expected behavior: Program compiles and runs

Additional Information: This was tested across behaviors. I did not actually test whether it happens within the same behavior.

Same problem and it happens within the same behavior.
