Well, yes. You can do everything yourself (you don't need to use the 
unittest system for this BTW). What I meant to say is, if you want to 
run all unit tests linked into the program, regardless of compile-time 
introspection, you need to rely on the compiler/linker to gather those 
for you (they are all provided as part of the ModuleInfo items), the 
compiler does not store references to individual tests.

The things you *could* do are:

1. Print out messages for each module run, even if they pass
2. Colorize the output of those messages
3. Run unittests of specified modules only.

UDAs are also not provided to the ModuleInfo, so there isn't a way to 
affect the standard unittest framework that way.
