What a Difference 8 Years Makes (In Code)

I spent some time this weekend rewriting 8 year old code. It's interesting to compare the pieces where the core logic resides.

Original:

New:

Now I'd like to jump ahead 8 years to see the code rewritten again (and bring it back with me).

Perhaps it will include declaring types again and not use "var". Presumably, the future-versions of us will see the folly of this trend and go back to being explicit, once we realize that "assumptions are the root of all software bugs"!! I'm not picking on you, I'm just saying - I don't agree with this trend... :-)

Although "var" is not the same as used in dynamic typed languages, eg. JavaScript. I think it really depends on when and where you should use it in C#.

That's easy: just write it in Clojure. :)

In short, I couldn't agree with Rob less - the code will be *less* statically typed, not more. Especially something like this...

It seems the two pieces of code are unrelated.

@Rob - I like var, so we'll have to agree to disagree!

@tobi - Right - it's hard to make a 1:1 screen shot. The original solution used a lot more code and never really expresses the essence of the solution, if you know what I mean.

@Chris - right!

@Craig - I think this code would look pretty good in Clojure. Hmm ....

In 8 years the code will be useless: M$ have already made it for you out-of-the-box. ;)

As far as I can tell, neither of these pieces of code is complete, although the first one looks close. The only reasonable comparison is complete correct code A vs complete correct code B

@beyondChairs - That is intentional. If you are looking closely at the code then you are missing the point ... :)

@scott - I think you're missing the (your) point. To say "I used to do this; now I do this" isn't really meaningful unless the two examples do the same thing.

@James, @beyond - ok, point taken.

This is the emperors new clothes and utterly pointless, but hey, who am I to upset your ego ?

Not possible, HMC ;)
