Interesting solution, just replacing the _moduleUnitTests() that 
normally runs them :).
(I guess that's the natural place to put it though)
Unfortunate about the ugly warning this produces ("usr/bin/ld: Warning: 
size of symbol `_moduleUnitTests' changed from 1084 in unittest_walker.o 
to 58 [...]").

Ah yes, forgot about that (failed unit tests aborting the program).




About your sample.d: It thinks I'm a Windows user who didn't compile 
Phobos with debug symbols :P.
In reality, I'm using GDC 0.23 on amd64 Linux.
It turns out GDC's std/math.d only declares isnormal() itself if on x86, 
otherwise it aliases gcc.config.isnormal() to do the job...
(Adding "version(GNU) if(!funcs) { funcs = "gcc.config.isnormal" in 
functions; }" right after the lookup should fix it)

Also, your struct example seems to have a typo (0x13_45_67_AB != 
0x1234567AB).

And some unit tests in flectioned.d fail:
