I think you don't need this dtor here.

[altimofeev, 2011/05/20 12:00:32]

Why?

[whywhat, 2011/05/21 19:26:58]

Empty dtor is automatically generated and it is virtual since the dtor of the
base class is virtual.

[altimofeev, 2011/05/23 08:13:58]

I understand it. But I think that a rule of always having explicit virtual dtor
in classes with virtual methods is a good thing, even supported by our style
guide?

OK
