Hi Oskar,
ctnr/refresh is a good way to reboot the REPL's state without having to
restart the process. To do this, it removes namespaces, then re-requires
them in dependency order.
If you have an error in one of your namespaces, that namespace and all
namespaces that depend on it will no longer be available, so you will
get "namespace not found".
There is probably a way to change fireplace to deal with this situation,
but for now you should be able to work around this by creating the
namespace manually from a namespace that does exist, like the `user` ns:
user=> (create-ns 'my.broken-ns)
The namespace will still be broken, but you should now at least see
compiler errors.
