Forbid the use of primary constructor's parameters.

Usage

partial class C([Field(Name = "_a"), [Field(Name = nameof(C._b))], Field, [Property(WithInit = true)]]int i) // type must be partial, but can be class / struct
{
# region Generated members
    // private readonly int _a = i;     // generated field
    // private readonly int _b = i;     // generated field (with computed name)
    // private readonly int _i = i;     // generated field
    // private int { get; init; } = i;  // generated Property
# endregion

    public void M0()
    {
        i++;                    // error on usage of i
        Console.WriteLine(i);   // error on usage of i
    }

    public void M1()
    {
        var i = 0;
        i++;                    // don't error on usage of locals
        Console.WriteLine(_i);  // automaticaly created readonly field
        Console.WriteLine(_a);  // automaticaly created readonly field based on Name property
        Console.WriteLine(I);   // automaticaly created readonly property
    }
}

To enable the feaure, type [Field] or [Property] before the primary parameter you want.

You can type as many attributes as you want on a single parameter.
