Hi *,

this rule is usefull in the case where you use common names for
attributes (such as x, or y), and accidentially "overwrite" them as
parameters. This again comes back to the point of readability.

The same variable name should ALWAYS refer to the same variable / value.

For setters and constructors this makes sense -> after all, in each of
these you have a simple assignment, and both variables will carry the
same value.

But in most other methods, the parameter you pass is NOT assigned to the
internal variable, so they actually refer to a different thing, and
thats where the confusion starts.

I know modern IDEs can show you which variable you actually refer to,
but this usually requires selecting the variable or hovering over it,
which you will not do if you are just reading the code trying to
understand it.

However, since we cannot agree to keep the rule, I'll have to be content
with removing it (which is already done).
