I still do this and it still works for me.  But...

I doubt it was intentional.  But there are still bizarre dependencies 
that no one has bothered to figure out or fix.  One issue that has 
bitten me is that when I compile or load some file, suddenly some 
variables are now special.   That's quite annoying.  But this was long 
ago, and my memory is likely faulty.
