Both of these look "clean" but i do not think that moving 3 lines to one line makes code "cleaner" They both do the same thing and if someone that does not know what .bar() .baz(param) and .frob() are IMO the second version that takes place on three lines would be easier to understand. >I'm generally +0 on this idea (it seems like the clarity in writing >comes largely for interactive users), and don't see much difficulty in >separating the constructs.

So, how is this different from the fact that >b = a[1:10:3] already returns a reference to 'a' >(I suppose in the fact that it actually returns a new object just one >that happens to share the same data with a). >However, I suppose that other methods don't return a reference to an >already-altered object, do they. >Tim's argument has moved me from +0 to -0 >-Travis I couldn't agree more with you and Tim on this. I would rather have code that works all the time and will not possibly confuse people later, like the example of >b = a.sort() >and think you have a new array, but in fact have a new reference to the >already-altered 'a'? alot of people have problems grasping this "memory management" type of programming...or at least in my C class half of the kids dropped out because the couldnt keep track of b = a.sort() meaning that b was actually just referencing a and if you changed b then a was changed also. But then again who on this list has problems remembering things like that anyways right?... ~Kenny ------------------------------------------------------------------------- Using Tomcat but need to do more?
