In your other message, you said this wasn't a legitimate CPython
complaint. Here, you say that it would be a "complex hack" to
implement
this in CPython. �"complex hack" has negative connotations in my mind.
This seems contradictory to me.
Well, you missed the point, chief.
It's not a legitimate complaint because you can use xrange, you don't
need compiler magic to recognize and optimize range.
There's a lot of things in Python that I don't strictly *need*. That
doesn't mean that they wouldn't be welcome if I could have them.
Getting rid of the range/xrange dichotomy would improve things. Yes, I
can work around it until the runtime is good enough to let me think
about an *interesting* problem instead. That makes it a legitimate
complaint in my eyes. You're welcome to disagree, of course, but do you
have an argument more compelling than the one you give here? It seems
to me one could use it to argue a lot of Python out of existence.
Chief. (Seriously, "chief"? What are you going for? It sounds like
condescension to me; what's the point of that? I hope I'm just
misreading you.)
