Hmm.. safe, but what about void methods? Silently not invoking methods
seems like a bad idea to me.

Oops! :P

The Elvis operator looks kind of neat though. Although in D it's a bit
challenging since cast(bool) doesn't always do what you want. E.g. it
returns false on non-initialized string, true on zero-length
initialized string.
