You *always* need to use a tool anyway, even if that tool is just
called "Thunderbird."

That's no different than from any other setup where you have source
and object code, and we've learned how to deal with it quite well. Or
alternatively, think of "tar" und "untar" for distributing code.

I am quite sure that we currently cannot.  The philosophical
differences between the various approaches are far too great.  Believe
me---we've tried very hard to bridge them, but without success so far.
One of the problems is that there's no agreement on what problems a
module system should really solve.  In the end, we agreed that the
requirements we were trying to address were mostly code distribution
and use, and the current proposal tries to do that quite specifically.

Moreover, there's still a lot of ongoing research that I expect to be
of significant practical impact in the years to come, which I'd prefer
not to block by setting in stone something inferior now.
