The way 'use-project' is implemented, it's rather integrated with
project loading. You can try project.use, see how load-used-projects
in project.jam uses that.

Generally, maybe rules in project-rules module need a current project,
and to call them, you need to know the current project somehow.
One way to know the current project is the project.current rule.
Note that it returns valid value only when a Jamfile is being read. After
Jamfile is read, the return value is not meaningful.
