Just watched Rich Hickeyās āSpec-ulationā talk and I feel like spec is designed for library developers, not app developers. The constraints he talks about make sense for libraries, but feel like they seriously limit the usefulness of spec for app developers.
When Iām building an app I donāt care if I make breaking changes. I can manage that. The cost of doing so is vastly less than the cost of keeping all the old app code around.
