Given how trivial the
isEOF
function is, we can simply inline the check at the various call-sites and remove the function (which ought to be ever so slightly more efficient as well).Furthermore, this patch also changes the
EOF
primitive itself to aSymbol
instead of an Object since that has the nice benefit of making it unclonable (thus preventing accidentally trying to sendEOF
from the worker-thread).
