It's actually Haskell's fmap, which we have in the form of .map for both
Option[1] and Result[2], e.g. the proposed expr->method() is the same as
expr.map(|x| x.method()) (which is still quite verbose).
The return value of .method() is actually a Result/Option so it would be more
similar to .and_then:
foo->bar()
// would be the same as
foo.and_then(|x| x.bar());
