A test case, probably can be reduced futher:

@trusted public struct RleBitSet(T)
{
public:
    @property auto byInterval() pure const
    {
        static struct IntervalRange
        {
            this(in RleBitSet set_)
            {

            }            
        }
        return IntervalRange(this);
    }

}

immutable set = RleBitSet!(uint).init;

pure void func()
{
    auto x = set.byInterval;    
}


Tested on DMD 2.060 beta. Compiler flags seem to have no effect.

Output:
bug.d(14): Error: pure function 'byInterval' cannot call impure function 'this'
