Not necessarily implicit conversion, but implicit construction.

The nicety with D's overloading rules are they are simple -- if there is 
an exact match, use it. If there is a conversion possible, use it. If 
multiple conversions are possible, ambiguity error.

Adding another way to convert doesn't seem like it would cause lot's of 
complication or harm.
