Generic type that extends bool

How can I make my generic type "extend" boolean?

c#
class MyClass<T> where T : bool {
}

c#
class MyClass<T> where T : bool {
}

That generic parameter would be quite useless, wouldn't it? System.Boolean is a sealed record, so you can't extend it The only possible route is composition, basically

class MyClass
{
    private bool _value;
}

class MyClass
{
    private bool _value;
}

and maybe explicit cast operators And other overloads that would make it compatible with bool

im pretty sure that all base types are sealed to avoid program obfuscation (complications) things like strings, bools, ints, etc

They're sealed because they're not classes. They're value types in the CIL, and you cannot inherit from value types. But they're also primitives.
