The ? operator now desugars expr? to a match expression that unwraps Ok
values and early returns Err values:
match expr {
Ok(#ok) => #ok,
Err(#err) => return Err(#err),
}
Implementation details:
- Use pre-interned identifiers (#ok, #err) for synthetic variables
- Use pre-interned Ok/Err tag names from CommonIdents
- Create applied_tag patterns for Ok and Err
- Build match branches with proper scope isolation
- Mark synthetic patterns as used to avoid unused variable warnings
- Create e_lookup_local, e_tag, and e_return expressions for branch bodies
