The order of loading the libraries defined within a bootstrap file is defined. This should solve this problem. I don't see a reason
for complicating the syntax by introducing dependency rules.

I actually like this proposal, but see also some possible problems here (what happen's if the environment variable is not defined,
we just recently scrubbed the environment variables due to possible side effects, ...). But in this late stage I am very hesitant to
change anything, suggest to delay this discussion for 3.2.

Although I understand where you are coming from, I think this would be a significant add-on and complicate things too much.

Already answered in an earlier email.
