Could Revise warn about "Method overwriting is not permitted during Module precompilation"?

[NHDaly]

If you add a duplicate method to a package while a REPL is running Revise, you don't get any kind of warning from Revise.

So you could continue happily editing your project, not realizing you have a duplicate, and then be very surprised when you restart the REPL and it complains about the precompilation failure due to duplicate methods. You may even have forgotten about adding that method by the time you finally see the warning.

It would be nicer if we could give a warning right away, as soon as the duplicate was added.
Or even do the nice thing where Revise goes yellow until it's fixed?

My colleague @mabokhamis reports that they have a reproducible test failure that seems to be caused by duplicate methods, and our mutual colleague didn't understand the cause of the test failure until Mahmoud tried to reproduce it and noticed the precompile warnings.

It would be great if the original author had gotten a warning or error earlier! :)

Thanks! :)
