Object a;
causes the constructor for Object to be called.
Object *pa;
does not (as I expected), but
pa = new Object;
does, which I suppose I also expected.
If it doesn't exist then the compiler gives up. Interestingly, gcc reports the constructors it does find, and I noticed that if I define no constructors at all for Object, then there is no complaint from the compiler, but if the only one I define is an unsuitable candidate, then gcc reports trying both my constructor and Object::Object(const Object&).
This is really confusing, it suggests that if no constructors are defined, then one for no arguments is created by default; but if one is defined, then a copy constructor is created by default??

Quick
- ($a, $b....) = unpack("A2A7...", $packed)
- push( array, list )
