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'
