It compiled without error.  So...
1) The compiler didn't check for safety
2) It counts as safe if you only modify local-to-the-class variables 
(and I misunderstood).
or
3) This error is only detected on execution

But which?

(I'm still writing the code, so I can't yet try to execute it, and I 
took off the safe annotation because after I read the definition in TDPL 
it seemed a mistaken annotation.  But perhaps I misunderstand.)

Please don't post in Announce for questions, Learn would be a 
better place.

For your problem, reading the list 
http://dlang.org/function.html#safe-functions I'm not sure what 
is unsafe in what you do.
