• Use metaclasses sparingly; they add complexity.
• Prefer composition and decorators for simpler use cases.
• Document your metaclasses thoroughly for maintainability.

You can chain multiple generators to create data pipelines. For example:

def generate_numbers(start, end):
    for i in range(start, end):
        yield i

def filter_even(numbers):
    for num in numbers:
        if num % 2 == 0:
            yield num

def square(numbers):
    for num in numbers:
        yield num ** 2

# Chaining
numbers = generate_numbers(1, 10)
even_numbers = filter_even(numbers)
squared_numbers = square(even_numbers)

print(list(squared_numbers))  # Output: [4, 16, 36, 64]
