Terry's still right: correctness comes *first*, even if both are
"vitally important". Only once you have the thing correct (as proven by
passing tests) should you focus on speed.
This leaves aside the possibility that you should consider speed before
even picking your programming language, architecture, hardware, and
such, which of course for a problem requiring *real* speed would come
first. This thread was about a small detail of Python performance and
the possibility of having the compiler do some optimizing, however, and
these are not concerns that would show up in the initial stage of such a
project.
