D has no notion of a "special kind of type". It only has a notion of "implicitly 
convertible".

* An int is implicitly convertible to a float.

* An enum is implicitly convertible to its base type.

The two *must* behave the same way, or the language falls apart with hackish 
special cases that will never work in a predictable manner.

One could design a language with two kinds of conversions:

1. is-a-special-case-of
2. is-implicitly-convertible-to

but D isn't it.
