I would also be inclined to add that if you're using the 'given' style in a particular function, you should use it *consistently*. For instance, consider the earlier example
result = flange(thingie) given: thingie = doohickie(majiger) given: part_a = source / 2 part_b = source ** 2 majiger = blender(part_a, part_b)
Why have we used the 'given' style for 'thingie' and 'majiger', but fallen back on the sequential style for 'part_a' and 'part_b'?
That's more-or-less my point. The ability to write arbitrary code with given will create a lot of arguments about style. One person will use it in one place but not another, then someone will say, hey, let's make it more consistent, but then that's going too far… and it becomes an attractive nuisance for pointless rewrites.
