Hi
I have a construction like the following

if (source) {
  if (source.pool) {
    if (source.pool.repository) {
      if (source.pool.repository.directory) {
        if (source.pool.repository.directory.users) {
          // do something

Any chance to simplify this nested ifs?
I know some languages has a way like.

if (source?pool?repository?directory?users) // do something


Similar ways in D?

Thanks and Regards, Ozan

You need the null conditional operator which is not available in 
D.
