Re:Show HN: Fo: An experimental language which adds generics... by andrewstuart2 on Tuesday June 12, 2018 @03:05PM (#17296778)
No, you have to use reflection to determine the type at runtime. Generics use the compiler to prove the type at compile time so that the runtime can forego the much-slower reflective code paths.
