`LightScopeOf` Doesn't See Through Layers of Templates

[jmh530]

I have a referenced-counted stairs object that I want to pass to another function. It requires calling lightScope on it to strip the RC context. I think the way to do that is to make sure that LightScopeOf works for it, but it looks like when the iterator is a StairsIterator, then LightScopeOf just returns the same type. Ideally it should just be a simple fix to adjust how LightScopeOf works to get working.

unittest {
    import mir.ndslice.iterator: StairsIterator;
    import mir.qualifier: LightScopeOf;
    import mir.rc: RCI;

    static assert(is(LightScopeOf!(StairsIterator!(RCI!double, "+")) == StairsIterator!(RCI!double, "+"))); //passes but shouldn't (ideally)
    static assert(is(LightScopeOf!(StairsIterator!(RCI!double, "+")) == StairsIterator!(double, "+"))); //fails, but should pass (ideally)
}
