I created a Vagrant virtual machine using their "ubuntu/trusty64" box (
https://atlas.hashicorp.com/ubuntu/boxes/trusty64).
I connected to it via "vagrant ssh"; that gave me a shell prompt. I can't
remember whether that gave me a root prompt or not; if it didn't, then I'd
have typed "sudo -s".
I
C-x C-f /tmp/wat.py RET
M-x toggle-debug-on-error RET
x = [ RET
That leads to this error:
Debugger entered--Lisp error: (wrong-type-argument number-or-marker-p
nil)
