DMD can implicitly convert class pointer to the bool. Is it bug or terrible feature?

Not at all, and most people coming from C/C++ would likely be annoyed to not 
have it. And a prime place that it's used where using is woludn't work is with 
the in operator. e.g.

if(auto ptr = key in myAA) {...}

Granted, that's a pointer rather than a class reference, but it's essentially 
the same issue. And I see no reason to have pointers and references act 
differently in this regard.
