So, the actual problem is that given both

   datetime/package.d and
   datetime.d,

the import statement prefers the file. It could produce a compilation error.

If we don't want that extra check by the compiler, it would be better to 
keep datetime.d with a warning in it about the change. The warning could 
say "please remove this file". :)
