11 This assumes that the person doesn't do it manually in Python and
12 doesn't make use of already implemented functionality (eg. qsort) in C,
13 which jumps out as the first Google result; generalizations like these
14 are subjective, because it's just your view and thoughts of reality.

21 Indeed, a lot of us are CompSci students have that algorithmic
22 complexity drilled in since the first year. If we need performance,
23 we'll put it to great use; an occasional prototype, not so much.

31 Actually, language doesn't even matter here; just push that power off
32 button 'n get back to paper, then fix it in even faster pseudo code. :)
34 (Well, unless you type pseudo code faster than you write it down ... :P)
