To bad I've accidentally removed all comments in property-set.jam and never
took the time to rewrite them. The class is special the the sense then there
never two different instances with the same value returned by the "raw"
method. That's why it's possible to compare instances.

Oh! Thanks for taking the time.

Yes, that's used in some other places where actions are not necessary.

You could do:
Jamfile_text = t.expand_toolset("""
exe a : a.cpp : : release ;
exe a : b.cpp : <toolset>$toolset : release ;
But existing tests are fine with me. I've applied and comitted your patch.
Thanks a lot!
