Feature request: eslint-disable-block or eslint-disable-next

This is one almost real part of my code:

function unbindNode(object, key, node, eventOptions) {
    if(typeof this === 'object' && whatever) {
        eventOptions = node;
        node = key;
        key = object;
        object = this;
    } else {
        checkObjectType(object, 'unbindNode');
    }
...

no-param-reassign shows errors “Assignment to function parameter…”. It’s OK but I need to use eslint-disable-line for every line of the if block. I have almost the same code in tens of files and I really don’t want to disable the rule globally.

I hope this proposition makes sense. At least istanbul has very similar feature /* istanbul ignore next */

You can use /* eslint-disable rule-name */ and /* eslint-enable rule-name */ within the block. Note that those have to be block comments, not line comments.

Yes, that’s two comments instead of one, but better than one per line.

My voice may be in the minority, but I would also like the ability to disable a rule per function. A common use case is decorating an object with extra properties, or updating summary/total properties. ESLint will complain with no-param-reassign about each assignment to properties of the object.

function decorateObject(object) {
    ...
    object.someSummaryProp = ...  // eslint-disable-line no-param-reassign
    object.extraProperty1 = ...  // eslint-disable-line no-param-reassign
    object.extraProperty2 = ...  // eslint-disable-line no-param-reassign
}

I’d rather not add // eslint-disable-line no-param-reassign after each line that computes a new property for the object.
