Problem

Given a positive integer n, build the sequence 1^2, 2^2, ..., n^2 in order. Internally generate the squares lazily with a generator (one square at a time), but return them collected into a list. For example, squares_up_to(5) returns [1, 4, 9, 16, 25].

Summary

A sequence that never fully reveals itself.
