Right, it would be the first command that does that.

I became quite convinced that conventions and, thus, implicit arguments
can occasionally improve usability.  We use tools that operate this way
daily: ‘make’, ‘git’, etc.  Dave nicely argued about it:

But yeah, it is a departure from what we’ve done so far, so we should
take the time to think through it.

Thanks,
