# Option[T] and safe navigation:
# Some languages have a specialized syntax for what is usually called "safe navigation"
foo?.bar[10]?.baz

# Option[T] could be implemented as a proxy type that rewrites any operation on it 
# as a operation applied to the stored value (if there is any)
# The original example then becomes:
Option(foo).bar[10].baz   # returns Option[type(baz)]

# Another point to note: proxy types used in this fashion are pretty much equivalent to Haskell's monads
