Is pattern-alt the only way to select from tag types, ie. I tried this code using iftag tt { a(); b();} fn main() { let tt t = a(); if (t == a()) { log "equal"; } } and got a compile error Fatal error: exception Failure("forcing non-scalar referent of type [b32,([]|[])] to register")
Yeah. This is a bug. At the moment comparisons in general only work between scalar types (int, uint, u8, char). Strings, records, tags, vectors are presently non-comparable. And not in a nice way: in a bug-thrown-by-compiler way.
