Do classes require explicit constructors?

Zero, because I absolutely hate doing it.

Same reason why I avoid class hierarchies like the plague.

There are some real irritants with it that don't need to exist.

To me yes.

 From Java, the experience was a total 180.

I went from yeah ok I need this exception, go declare it.
To let's just throw an Exception forget about doing this properly.

It breeds slop, which really grates on me.

Usually I can get away with ignoring these features, but with PhobosV3 I 
am unable to. I've already had to add new exception classes to druntime 
specifically for it as part of null check.

I want classes improved, there is plenty of room for it.
