Hello, today I stumbled upon this page:
http://confluence.jetbrains.net/display/Kotlin/Null-safety

There's so-called 'safe call operator' in Kotlin programming language
which, when used in chains, resembles 'Maybe' monad from Haskell. Thus it
makes easier to work with nullable types in some cases. Is it possible to
add such a feature to Vala?
