I updated

https://github.com/nordlow/justd/blob/master/containers_ex.d

as you say but now it errors as

/home/per/Work/justd/containers/hashset.d(46,19): Error: struct 
std.experimental.allocator.building_blocks.region.InSituRegion!(1048576LU, 4LU).InSituRegion is not copyable because it is annotated with @disable

Can't I use InSituRegion in this way?
