[REBOL] [BUG] unset!

[dolmen]

Look at that :

>> type? %f
== file!
>> type?
== unset!

So unset! seems to be a datatype.
Lets verify if unset! is a datatype :

>> type? file!
== datatype!
>> type? unset!
** Script Error: unset! has no value.
** Where: type? unset!

But :

>> type? type? %f
== datatype!
>> type? type?
== datatype!

So, is unset! a datatype! or not ?

This also has an impact when using "mold" and "do" :

>> do mold type? %f
== file!
>> do mold type?
** Script Error: unset! has no value.
** Where: unset!
