No, it will still separate the declaration, but just on the block level. For example: for i := 0 to n - 1 do var foo: integer = 0; begin // ... end; > When you look for a variable, you know it is in the declaration block. > If you need to start scanning the code, this is a major nuisance. If you're in a block, you look at the "var" section of the block first, then move up a block and repeat. Calling it "a major nuisance" is needless hyperbole. In the above code, why do I want to see foo in the main "var" block of the function? It's just noise there, reducing readability. > I can't count the misunderstandings in Javascript due to this 'feature'. This feature makes you properly reduce scope of variables, I seriously haven't met anyone that thinks this is a bad idea. It's standard programming practise in every language I've worked.
