I actually find it very useful.  For example, in dcollections, I test with  
every possible integer instantiation (ubyte, byte, ushort, short, uint,  
int, ulong long), and it has caught quite a few bugs, even compiler bugs!

Only drawback is it takes a long time to compile with all those  
instantiations!
