This doesn't need explicit anymore :)

Ah, okay, we just need explicit for single parameter constructors, correct?

[Devlin, 2014/09/12 00:26:46]

Right.  This stack overflow question does a good job of explaining. [1]  But
basically, explicit means that, if an object's constructor takes a single second
object, given that single object, you can implicitly convert to the first
object.  Very bad in the case of, say, a Browser object (which only needs a
Profile).

Yep, I found that with a quick google search :)  Just wanted to clarify that
that's something we always do for single parameter constructors.
