Sorry, I explained it badly ... let me try again:
what if a DOM event handler uses/creates/invokes inside its function body a
generator?
Will the event pause until this will be satisfied?
`a.addEventListener('click', function(e){ if(methodThatInvokesGenerator())
e.stopPropagation(); });`
Is this a concern?
Thanks
