all() performance and internals

Performance characteristics and CPython implementation details.

python
# all() internals
import dis

def using_all():
    pass

# Bytecode analysis
dis.dis(using_all)

# Check if it's truly built-in
import builtins
print(f"\nall is builtin: {hasattr(builtins, 'all')}")
print(f"Type: {type(builtins.all)}")

Understanding the internal implementation helps optimize hot paths in performance-critical code.
