Python's website does a great disservice to the language

[The Eternal Squire]

Well, I admit the remark was off the cuff because I was thinking of
conventional waterfall development cycles in the aerospace industry....
 in that context someone who wasn't there during an entire development
cycle is not even a junior member, but is rather a recruit under
training to begin actually contributing to the next project.

I would call someone who survived all phases of a single
design-code-test-peerreview cycle (about 2 years) to be junior, and
someone with less experience that that as a recruit.  On that basis,
the lead should have 3 design cycles or 6 years experience.   The lead
does not need to be the master designer on the project, but it helps a
lot when that happens.
