Can you explain specific features of your primary programming language and how they impact memory management or performance? For a practical demonstration in Python, implement a function that processes values lazily instead of creating an intermediate filtered list. Given an iterable of integers and a threshold, return the count, sum, minimum, and maximum of values greater than or equal to the threshold. Return None for minimum and maximum when no values qualify.
Function signature: def analyze_values(values, threshold):
def analyze_values(values, threshold):
