Those bug me because all it really wants from it is the name and 
then you need all the moduleinfo even in bare metal.

Exception support requires some RTTI anyway so maybe it doesn't 
matter, but my playing with bare metal has made me really prefer 
the filename versions over the moduleinfo versions...
