Add rules for this, delete, auto, lambda...

[LuisGP]

I want to call for discussing:

this

Applying the already defined rules, I don't see the need for using this under any circumstance, so I propose to forbid its use. Using it will hide the break of the code stylish defined here.

delete

To unify the usage of the delete operator I propose to use it always without parenthesis.

delete(pointer_); // Bad
delete pointer_; // Good

auto

I propose to define the rules for the usage of auto if any, and when it should be replaced by a concrete type, a typedef or a using.

typedef vs. using

If you are going to define an alias for an already defined type, then typedef is your keyword, but when you need to simplify a type to make the code more readable in a well-defined scope, then which keyword use and why?

lambda

Should we define a maximum length for lambda contents?

I agree with all changes, but if we allow the use of typedef and using as alias I will force to very restrictive cases (only when their usage really improve the readability). Do not allow to take free decisions to this.

For typedef vs. using discussion, read:

It appears that using is the winner (?)

[LuisGP]

So, they mean exactly the same.
using allows templates and is more readable in general.

My vote is going to using then.
