Phase 7.10: buxc2 now compiles multi-statement Bux programs
...
Parser (src_bux/parser.bux):
- Block stores statements as linked list (firstStmt/lastStmt/nextStmt)
- Block struct: added firstStmt, lastStmt fields
- Stmt struct: added nextStmt field
HIR Lowering (src_bux/hir_lower.bux):
- Lcx_LowerBlock: iterates statement linked list, chains HirNodes via child3
- hIf: else block stored in extraData (child3 reserved for block chaining)
C Backend (src_bux/c_backend.bux):
- hBlock: emits statements via child3 linked list with proper indentation
- hStore: combines alloca + value into single declaration (int x = value;)
- hIf: full if/else emission with proper newlines
- Function decl: proper return types and parameter types (not just "int")
- int main() wrapper: generated when Main function exists
- No duplicate return 0 when body already has return
Tested:
- buxc2 compiles hello world program → runs correctly
- buxc2 compiles multi-statement program (let, if, function calls) → runs correctly
- All 18 examples still pass, all unit tests pass

Phase 7.9: Self-hosted compiler buxc2 builds and runs! 🎉
...
buxc (Nim bootstrap) successfully compiles buxc2 (Bux self-hosted compiler)
into a working 88KB ELF x86-64 binary.
Compiler fixes (Nim):
- duplicate symbol: user funcs shadow stdlib funcs via mergeDecls()
- forward declarations: func without body + definition (both orderings)
- extern func dedup: same extern in multiple files
- discard keyword: new language keyword, lowered to expr stmt or no-op
- parser: keywords as field names + advance-on-error safeguard
- parser: var without initializer (zero-init)
- parser: multi-line || && continuation expressions
- parser: else-if chain newline handling
- C backend: const declarations emitted as #define
- C backend: load(field_ptr) → base.field optimization (fixes lvalue errors)
Source fixes (src_bux/*.bux):
- types.bux: tk* → ty* prefix for type kind constants (avoid token conflict)
- sema.bux: remaining tk* → ty* references, StringMap → *void workaround
- hir_lower.bux: ekReturn removed, Lcx_LowerParam helper, *f dereference
- c_backend.bux: &mod.funcs[i] for pointer passing
- cli.bux: ReadFile/WriteFile → bux_read_file/bux_write_file wrappers
- parser.bux: pathStr.len → String_Len(pathStr)
- types.bux: "*" + x → String_Concat("*", x)
Build system:
- Makefile: added 4 missing examples + selfhost target
- PLAN.md: updated with actual project state, Phase 7.9 marked complete
All 18 examples pass, all unit tests pass.
