Comment:
This patch (which is relative to the list comprehension patch, because it isn't likely to go in before listcomp, and they clash at a couple of places) adds built-in range-creation, exactly like the range() builtin, but without the ability to override the behaviour by masking the builtin with a global or local range() ;)

[10:100:2] is exactly the same as range(10, 100, 2). Assignment to range-literals is not possible, nor is 'chaining' them inside a single list. They do work well with list comprehension:

[ x * 2 for x in [1:100] if x % 3]

Also, the patch contains some code duplication (about the entire build_range function, plus get_len_of_range()) I'm not sure how to properly solve that: is it okay for compile.c to rely on something from bltinmodule.c ? If not, should I move the common functionality into listobject.c ?

Comment:
Oh, and before anyone gets the wrong impression, this idea was not mine; Guido suggested I try and implement it.
