Am I evil for this?

So I watched this video:

And Walter talked about using operator overloading for 
nonstandard purposes.

So in my collections library, I used it to implement set 
operators, but since set operators don't exist in the D standard 
(and require unicode, which would upset a lot of people, 
especially those who don't know what Win + '.' does), I had to 
use operators that have similar function in other spaces.

I personally haven't used them yet in my projects (except for the 
unittests), so it's not too late to remove them, but I don't know 
if anyone else might be using them or not.
