This is indeed a very good proposal. I am currently finding myself with the problem that a particular path NEEDS to be included before another one, and there is just no way that this works with bjam, is there?

There is, just put:

<include>a&&b

in requirements for relevant metatarget or project.

Unfortunately, this isn't completely foolproof. Given, <include>b&&a <include>a we'll end up with a b a.

It would work better if we used a topological sort. Isn't there already something like this for libraries?

Hmm, I swear the plan was to put values with "&&" to the front of the list, before splitting, but I cannot see the evidence this is actually done in the current code.

topological sort would work. another alternative, of course, it just don't sort include properties, but the performance consequences of that are still uncearl.
