Module and package with the same name

[Francois Retief]

Hello,

I have a quick question about modules and packages?  Why can a module not 
have the same name as a packages in D?

I have the following directory/file structure in mind:

kernel/hal.d
kernel/hal/cpu.d
kernel/hal/cpu/arm.d
kernel/hal/cpu/arm/arm7tdmi.d
kernel/hal/cpu/arm/boards.d
kernel/hal/cpu/arm/boards/netarm.d
kernel/hal/cpu/sh4.d
kernel/hal/cpu/sh4/sh7750.d
kernel/hal/cpu/sh4/boards.d
kernel/hal/cpu/sh4/boards/dreamcast.d
etc ...

As I see it, packages are the directories, while modules are the files.  But 
when I try it, (DMD v0.149) I get:

#  hal.d: module hal and package hal have the same name.

Is this expected behaviour? If so, why this limitation?

Cheers
  Francois
