- Conditionals (WHEN, UNLESS, IF, WHILE, UNTIL)
- Accumulation (COLLECT, APPEND, NCONC, SUM, COUNT, MAXIMIZE, MINIMIZE)
- Control (DO, RETURN, WITH, INITIALLY, FINALLY)

Types Extended (20 functions):
- Type definitions (DEFTYPE, TYPE-OF, TYPEP, SUBTYPEP, COERCE)
- Type specifiers (SATISFIES, MEMBER, AND, OR, NOT, VALUES, EQL)
- Numeric types (INTEGER-TYPE, FLOAT-TYPE, RATIONAL-TYPE, REAL-TYPE, COMPLEX-TYPE)
- Sequence types (ARRAY-TYPE, SIMPLE-ARRAY-TYPE, VECTOR-TYPE)

I/O Extended (12 functions):
- Binary I/O (READ-BYTE, WRITE-BYTE, READ-SEQUENCE, WRITE-SEQUENCE)
- File positioning (FILE-POSITION, FILE-LENGTH, FILE-STRING-LENGTH)
- Stream properties (STREAM-ELEMENT-TYPE, INPUT/OUTPUT/INTERACTIVE/OPEN-STREAM-P)

Progress:
- Previous: 592 functions (60.5%)
- Current: 732 functions (74.8%)
- Phase 8: COMPLETE ✅
- Next target: Phase 9 (90.0%, 880 functions)

Build status: ✅ Clean compilation (117 doc warnings only)
