Write this code:

function lazyEdit( load ) {
  const Load = lazy( load );
  return function LoadEdit( props ) {
    return (
      <Suspense fallback={ null }>
        <Load { ...props } />
      </Suspense>
    );
  };
}

It defines a Load local variable and uses it in the returned function, as a JSX component type.

But the @wordpress/no-unused-vars-before-return incorrectly flags it as unused:

Apparently the rule doesn't find the usage in a JSX markup that is nested inside a local function.
