In Alyssa's analyze-sequence, execute-sequence is running in runtime. But the solution in the text unrolls this procedure. for example: for ((lambda (x) (+ x 1)) 1),
Alyssa's analyze-sequence is (lambda (env) (execute-sequence (lambda ...) env)),
analyze-sequence in text is (lambda (env) ((lambda ...) env)).
