You can't and don't. That's not what logical const is for. That's what 
physical const is for, and it does a great job at that.

Can I just be clear: I am not anti-physical const. I'm just also not 
anti-logical const, which D is. Logical const is best for functional 
programming and physical const is best for concurrent programming. Both 
are important.
