Re: An idea to avoid a narrow class of bugs

[Rene Zwanenburg]

I like this idea, I've had some nasty bugs because of this when I 
just started with D.

But IIRC the language doesn't forbid use of the GC in 
destructors, meaning it's an implementation issue. I don't know 
what the problems involved in allowing allocations during sweeps 
are, but I'd prefer to have support for GC usage in destructors. 
Having to work around this limitation often results in a load of 
ugly and overly complex code that should have been only a few 
straightforward lines.
