Scala's Option[+A] type is really useful to accurately type optional values.
Its higher-order methods like map and getOrElse, as well as its pattern
matching capabilities, make it a pleasure to deal with.
However, as is well known, it incurs the cost of boxing every present value in
an instance of Some.
In some cases, this can cause performance issues.
scala-unboxed-option's UOption[+A], which stands for Unboxed Option, solves
this problem.
It retains the full API of Option[+A], including the fact that it is type
parametric.
