I want a Pony!
summary
Pony claims a statically checked type system that guarantees no data races, deadlocks, nulls or unhandled exceptions if the program compiles, using six reference capabilities (ref, val, box, iso, trn, tag) to control aliasing and ownership. It compiles to LLVM, uses an actor model with zero-copy message passing and a per-actor concurrent GC, and enforces moves/consumes and recover blocks to transfer ownership. A simple chat client demo exists; language is young (v0.9) but the features demonstrably run.
