I was not aware of synopsis. Both projects are very interesting but
their scope seems to be different. I understood that both use
reflection as a vehicle for their needs while Reflex only
concentrates on introspection and interaction with C++. Reflex does
also not try to parse C++ definitions itself but leaves this to
gccxml (a frontend of gcc) and subsequently processes it's xml output
to produce dictionary source code. My guess is, that it is very hard
to implement a C++ parser. So with Reflex the dictionary information
for any C++ definition which is compilable with gcc, can be produced.
What may also be important is, that reflection source code is
produced in a non-intrusive way and that interaction with objects
from the meta-level is possible.
