Right.

To clarify, I’d enable the debug engine for interactive use, but not for
‘-s’, ‘-c’, and when a script is passed as an argument (analogous to
what 1.8 does with the evaluators.)

Tracing and stepping are typically only used interactively, so that’s
OK.  Coverage and profiling can start a new VM that suits their needs,
à la ‘with-code-coverage’.

So my impression is that the behavior above would usually have no
drawbacks for the end user, in that it wouldn’t visibly reduce
functionality.

What do you think?

Thanks,
Ludo’.
