Your solution does not help these people use Phobos because the
compiler will be inserting calls to free in places they don't
want, which will slow down their program.
I think that because of that, the following should be possible:
Exception store;
catch(Exception e)
{ //does not call the destructor
store = new Exception(e.move);
//still no destructor called because e is null
}
In case of preallocated exceptions, thats ugly to do everywhere.
But it could be argued that so is relying on EH speed on the
first place! Form follows the function. Still, I agree that's a
problem.
