For what it's worth, I use Vavr extensively in Groovy applications and think its Try support is sufficient. What would be helpful is improvements in the inference of Closure signatures, since Vavr sometimes overloads an operation name with methods taking different functional interfaces, and the compiler makes me explicitly `as` the Closure.
