It's so useful that I have to go and look up what exactly it means (and
then I'm not much the wiser).


But I guess some people develop dependences on such features. If I
question some exotic feature in the Python group, there will always be
someone for whom it is indispensable.


(Never mind that Python lacks what to me are fundamental features such
as named constants, 'switch', records, enumerations, repeat-n-times
loops, static local variables, pass-by-reference, or goto.


Some of those can apparently be emulated - usually badly and
cumbersomely - by making use of the advanced features.)


The trouble is, if you dare to put forward such a point of view, someone
is going to mention the 'blub paradox', just to put you in your place.

[Python certainly has a lot of theology. I believe that python users
would say that your misssing features are implemented through simple
idioms and aren't worth gunking up the languages, e.g. repeat N times
is "for i in range(N):". But like I said, it's theology. -John]
