[M3devel] external in module?

I wasn't going to write the code, so no need to worry.
However, if this is not the solution we aim at, then we need to
do something else about the increasing probability of the builder
failing because some module in a completely different package
which I don't even use directly happens to have the same name
as my internal module and thus cannot be compiled. Or even worse:
if I use two packages that happen to contain one module of the
same name and have never been used together before.

     computing: when a computer you didn't even know existed
     can render your own computer unusable :)
