Operation not permitted when piping in stdin

I wanted to write a simple smoke test, but this is where I ended up:

$ ilua << EOF
print"test"
EOF

I think that issue should be solved at jupyter frontend's scope. Other kernels could benefit from such feature too.

ilua is really just a thin wrapper around jupyter-console --kernel lua, so jupyter should handle the input redirection.
