D code obfuscator

[DigitalDesigns]

Is there an obfuscator for D that at least renames identifiers? 
This is because sometimes they leak from various processes and 
could be potential sources of attack.

It would be a tool that probably just replaces their values with, 
say their hash + something else and done pre release build. 
Ideally it would be able to compile with dmd and all in memory or 
use temp storage without file issues. It can't modify the code 
directly because then that would be permanent.
