[Boost-build] Question about calling rules from within a generator

I was trying to use the assert module to check various assumptions
within my custom generator class when I found it is not possible to
call those rules.  This is also true of other user-defined rules
within the same file as the generator.  Is this expected?

See the attached file for a minimal example that shows the issue.  The
project will run correctly after commenting out the call to
`assert.true` in `g.jam`.

Best,
Tom
