Hmm, doesn't "=void" simply skip nulling/initializing the value? http://www.digitalmars.com/d/changelog.html#new0126 xs0

This is only documented for arrays. http://www.digitalmars.com/d/memory.html#uninitializedarrays Thomas -----BEGIN PGP SIGNATURE----- iD8DBQFDELPR3w+/yD4P9tIRAtKhAKCWq2u5TfGwxpyVo35GPcK23y4MBQCgo64C Tu42+N0/oI1VU3TweNkLDhw= =YoVP -----END PGP SIGNATURE-----

It is legal and means the initialization is skipped. Perhaps it's poorly documented.

The only section documenting the VoidInitializer is "Allocating Uninitialized Arrays On The Stack" and talks only about arrays, and not about primitive/class/struct/union/enum.
