and what does it mean by sending "ns"?

when sending "eval" op, there's an optional argument called ns

This is the ns the code will run in

sounds reasonable, but what if I send nothing in the ns field?

Jon: I'm pretty sure it defaults to "user"

oh... thanks

It uses the session’s bound value of *ns* – this is initially user, but might subsequently change (e.g. by in-ns)
