  #1 is definitely not meh, it's actually really practical if you're doing real work in Lisp. It seems meh if you're doing academic "basic CS concepts" exercises in Lisp, though. > #3 re Python (and intial mention that languages arent written in themselves) just sounds like author is not up to date with modern python. Python 2.7.1 (r271:86832, Nov 27 2010, 18:30:46) [MSC v.1500 32 bit (Intel)] on win32 Type "copyright", "credits" or "license()" for more information. >>> def foo(): x = 0 def bar(y): x += y return x return bar >>> baz = foo() >>> baz(3) Traceback (most recent call last): File "<pyshell#10>", line 1, in <module> baz(3) File "<pyshell#7>", line 4, in bar x += y UnboundLocalError: local variable 'x' referenced before assignment Is 2.7.1 not "modern" enough? I was under the impression that a lot of people are still on 2.7 rather than switching to Python 3. (I switched to Lua for scripting; it has working closures, lambdas, tail recursion, etc.)
