Compare for example this:
both applications do similar things; print the "kind" (type,
etc.) of a member of a namespace and its name.
The first uses compile-time reflection, the second uses run-time reflection
and the run-time meta-objects are based completely on the compile-time
Also, in the run-time case, there is nothing (that I know of) preventing you
from using just the meta-object interfaces in your application,
compiling their implementations (the actual meta-objects) into a separate
dynamic library / shared object and loading and querying them on demand
from the application.
for more examples of compile-time vs. run-time reflection see here:
