Can we add testing and benchmarking?
Testing feels like it has been ignored pretty-much since forever, but it may be too big a task and probably deserves its own workgroup.
Benchmarking can also be difficult when working with an unfamiliar platform. I've been wondering if we could create a SwiftPM plugin with presets for common benchmarking tasks (tracking allocations, etc) on Linux and other platforms where Instruments is not available. I think something like that could possibly fit under a tooling workgroup.
