pragma disable for noUnusedLocals?

Question

I've turned on noUnusedLocals but I have a function that just checks for the existence of the first element but doesn't use it. Is there a pragma to turn this warning off for a code block?

Example:

export function has<T>(sequence: Iterable<T>): boolean {
    for (let element of sequence) {
        element; // Needed to quiet compiler setting `noUnusedLocals`.
        return true;
    }

    return false;
}

The docs say to use _:

Parameters declaration with names starting with _ are exempt from the unused parameter checking.

(See this)

But that only seems to apply for parameters, not local variables.

Answer 1

This is not really an answer in the strictest sense but _ as a name or name prefix suppresses --noUnusedLocals in for..of loop declarators in TypeScript 2.2.2 which is the current release at the time of this writing.
