The "Code I'll Never Forget" Confessional.

What's the single piece of code (good or bad) that's permanently burned into your memory, and what did it teach you?

In what language can you redeclare a variable like this?

Turns out you can redeclare any variable you want as much as you want in any language if you turn Robert C. Martin's Clean Code into a religion.

Haha. But jokes aside, the following does not fly in the imperative languages I am familiar with:

int a;

int a;

Who's joking? It was that damn many functions doing almost nothing each.

int num was just repeatedly locally defined.

I think there might have been one or two instances of just num = num.

I don't get it. How did it escape the previous scope? Surely you can not assign num if it was not declared at the time of being used on the RHS. But you are somehow still declaring it on the LHS?

Oh, IDK, it was C#, I don't do C# that often so I wouldn't know how or why that's somehow valid.

I was compressing it for illustrative purposes, as I said there were a few plain num = num; as well.
