Pattern matching looks cool but I have some concerns. What is the best forum for Rust discussion? I get the feeling HN would rake me over the coals for bringing up switch, falling through case labels and of course, goto.
Although, our pattern matching is a strict superset of C's switch (other than fall-through). But yeah, fall-through and goto aren't supported yet, and if we were to get them (in safe code), they may have to be restricted to preserve memory safety.
