Namespace prefixes don't need to be created before we use them.
The point is just that `debugger-` is already used by definitions (in
`debug.el`) so we can reuse that space instead of messing up pristine
real estate.

Oh, god, I didn't know (or forgot) about that horror.
We should throw it out: your code should make it obsolete.
E.g. we can take your new code as the default value of `debugger` and
only replace it with `#'debugger` when an interactive frame
is available.
